Fields

accesskey: Option<AttributeValue<'life>>

Provides a hint for generating a keyboard shortcut for the current element. This attribute consists of a space-separated list of characters. The browser should use the first one that exists on the computer keyboard layout.

autocapitalize: Option<AttributeValue<'life>>

Controls whether and how text input is automatically capitalized as it is entered/edited by the user. It can have the following values:

• off or none, no autocapitalization is applied (all letters default to lowercase)
• on or sentences, the first letter of each sentence defaults to a capital letter; all other letters default to lowercase
• words, the first letter of each word defaults to a capital letter; all other letters default to lowercase
• characters, all letters should default to uppercase

autofocus: Option<AttributeValue<'life>>

Indicates that an element is to be focused on page load, or as soon as the <dialog> it is part of is displayed. This attribute is a boolean, initially false.

autopictureinpicture: Option<AttributeValue<'life>>

A Boolean attribute which if true indicates that the element should automatically toggle picture-in-picture mode when the user switches back and forth between this document and another document or application.

autoplay: Option<AttributeValue<'life>>

A Boolean attribute; if specified, the video automatically begins to play back as soon as it can do so without stopping to finish loading the data.

Note: Sites that automatically play audio (or videos with an audio track) can be an unpleasant experience for users, so should be avoided when possible. If you must offer autoplay functionality, you should make it opt-in (requiring a user to specifically enable it). However, this can be useful when creating media elements whose source will be set at a later time, under user control. See our autoplay guide for additional information about how to properly use autoplay.

To disable video autoplay, autoplay="false" will not work; the video will autoplay if the attribute is there in the <video> tag at all. To remove autoplay, the attribute needs to be removed altogether.

In some browsers (e.g. Chrome 70.0) autoplay doesn't work if no muted attribute is present.

class: Option<AttributeValue<'life>>

A space-separated list of the classes of the element. Classes allow CSS and JavaScript to select and access specific elements via the class selectors or functions like the method Document.getElementsByClassName().

contenteditable: Option<AttributeValue<'life>>

An enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values:

• true or the empty string, which indicates that the element must be editable;
• false, which indicates that the element must not be editable.

contextmenu: Option<AttributeValue<'life>>

The id of a <menu> to use as the contextual menu for this element.

controls: Option<AttributeValue<'life>>

If this attribute is present, the browser will offer controls to allow the user to control video playback, including volume, seeking, and pause/resume playback.

controlslist: Option<AttributeValue<'life>>

The controlslist attribute, when specified, helps the browser select what controls to show for the video element whenever the browser shows its own set of controls (that is, when the controls attribute is specified).

The allowed values are nodownload, nofullscreen and noremoteplayback.

Use the disablepictureinpicture attribute if you want to disable the Picture-In-Picture mode (and the control).

crossorigin: Option<AttributeValue<'life>>

This enumerated attribute indicates whether to use CORS to fetch the related video. CORS-enabled resources can be reused in the <canvas> element without being tainted. The allowed values are:

anonymous

Sends a cross-origin request without a credential. In other words, it sends the Origin: HTTP header without a cookie, X.509 certificate, or performing HTTP Basic authentication. If the server does not give credentials to the origin site (by not setting the Access-Control-Allow-Origin: HTTP header), the resource will be tainted, and its usage restricted.

use-credentials

Sends a cross-origin request with a credential. In other words, it sends the Origin: HTTP header with a cookie, a certificate, or performing HTTP Basic authentication. If the server does not give credentials to the origin site (through Access-Control-Allow-Credentials: HTTP header), the resource will be tainted and its usage restricted.

When not present, the resource is fetched without a CORS request (i.e. without sending the Origin: HTTP header), preventing its non-tainted use in <canvas> elements. If invalid, it is handled as if the enumerated keyword anonymous was used. See CORS settings attributes for additional information.

data: BTreeMap<&'life str, AttributeValue<'life>>

Forms a class of attributes, called custom data attributes, that allow proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.

dir: Option<AttributeValue<'life>>

An enumerated attribute indicating the directionality of the element's text. It can have the following values:

• ltr, which means left to right and is to be used for languages that are written from the left to the right (like English);
• rtl, which means right to left and is to be used for languages that are written from the right to the left (like Arabic);
• auto, which lets the user agent decide. It uses a basic algorithm as it parses the characters inside the element until it finds a character with a strong directionality, then it applies that directionality to the whole element.

disablepictureinpicture: Option<AttributeValue<'life>>

Prevents the browser from suggesting a Picture-in-Picture context menu or to request Picture-in-Picture automatically in some cases.

disableremoteplayback: Option<AttributeValue<'life>>

A Boolean attribute used to disable the capability of remote playback in devices that are attached using wired (HDMI, DVI, etc.) and wireless technologies (Miracast, Chromecast, DLNA, AirPlay, etc.).

In Safari, you can use x-webkit-airplay="deny" as a fallback.

draggable: Option<AttributeValue<'life>>

An enumerated attribute indicating whether the element can be dragged, using the Drag and Drop API. It can have the following values:

• true, which indicates that the element may be dragged
• false, which indicates that the element may not be dragged.

enterkeyhint: Option<AttributeValue<'life>>

Hints what action label (or icon) to present for the enter key on virtual keyboards.

exportparts: Option<AttributeValue<'life>>

Used to transitively export shadow parts from a nested shadow tree into a containing light tree.

extra: BTreeMap<&'life str, AttributeValue<'life>>

/// Extra attributes of the element. This is a map of attribute names to their values, and the attribute names are in lowercase.

height: Option<AttributeValue<'life>>

The height of the video's display area, in CSS pixels (absolute values only; no percentages).

hidden: Option<AttributeValue<'life>>

An enumerated attribute indicating that the element is not yet, or is no longer, relevant. For example, it can be used to hide elements of the page that can't be used until the login process has been completed. The browser won't render such elements. This attribute must not be used to hide content that could legitimately be shown.

id: Option<AttributeValue<'life>>

Defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).

inert: Option<AttributeValue<'life>>

A boolean value that makes the browser disregard user input events for the element. Useful when click events are present.

inputmode: Option<AttributeValue<'life>>

Provides a hint to browsers about the type of virtual keyboard configuration to use when editing this element or its contents. Used primarily on <input> elements, but is usable on any element while in contenteditable mode.

is: Option<AttributeValue<'life>>

Allows you to specify that a standard HTML element should behave like a registered custom built-in element (see Using custom elements for more details).

itemid: Option<AttributeValue<'life>>

The unique, global identifier of an item.

itemprop: Option<AttributeValue<'life>>

Used to add properties to an item. Every HTML element may have an itemprop attribute specified, where an itemprop consists of a name and value pair.

itemref: Option<AttributeValue<'life>>

Properties that are not descendants of an element with the itemscope attribute can be associated with the item using an itemref. It provides a list of element ids (not itemids) with additional properties elsewhere in the document.

itemscope: Option<AttributeValue<'life>>

itemscope (usually) works along with itemtype to specify that the HTML contained in a block is about a particular item. itemscope creates the Item and defines the scope of the itemtype associated with it. itemtype is a valid URL of a vocabulary (such as schema.org) that describes the item and its properties context.

itemtype: Option<AttributeValue<'life>>

Specifies the URL of the vocabulary that will be used to define itemprops (item properties) in the data structure. itemscope is used to set the scope of where in the data structure the vocabulary set by itemtype will be active.

lang: Option<AttributeValue<'life>>

Helps define the language of an element: the language that non-editable elements are in, or the language that editable elements should be written in by the user. The attribute contains one "language tag" (made of hyphen-separated "language subtags") in the format defined in RFC 5646: Tags for Identifying Languages (also known as BCP 47). xml:lang has priority over it.

loop_: Option<AttributeValue<'life>>

A Boolean attribute; if specified, the browser will automatically seek back to the start upon reaching the end of the video.

muted: Option<AttributeValue<'life>>

A Boolean attribute that indicates the default setting of the audio contained in the video. If set, the audio will be initially silenced. Its default value is false, meaning that the audio will be played when the video is played.

nonce: Option<AttributeValue<'life>>

A cryptographic nonce ("number used once") which can be used by Content Security Policy to determine whether or not a given fetch will be allowed to proceed.

part: Option<AttributeValue<'life>>

A space-separated list of the part names of the element. Part names allows CSS to select and style specific elements in a shadow tree via the ::part pseudo-element.

playsinline: Option<AttributeValue<'life>>

A Boolean attribute indicating that the video is to be played "inline", that is within the element's playback area. Note that the absence of this attribute does not imply that the video will always be played in fullscreen.

popover: Option<AttributeValue<'life>>

Specifies that the element should be treated like a popover. An element with the popover attribute is hidden from the page unless it is opened by interacting with an invoking element that has popovertarget, or via showPopover().

poster: Option<AttributeValue<'life>>

A URL for an image to be shown while the video is downloading. If this attribute isn't specified, nothing is displayed until the first frame is available, then the first frame is shown as the poster frame.

preload: Option<AttributeValue<'life>>

This enumerated attribute is intended to provide a hint to the browser about what the author thinks will lead to the best user experience regarding what content is loaded before the video is played. It may have one of the following values:

• none: Indicates that the video should not be preloaded.
• metadata: Indicates that only video metadata (e.g. length) is fetched.
• auto: Indicates that the whole video file can be downloaded, even if the user is not expected to use it.
• empty string: Synonym of the auto value.

The default value is different for each browser. The spec advises it to be set to metadata.

Note:

• The autoplay attribute has precedence over preload. If autoplay is specified, the browser would obviously need to start downloading the video for playback.
• The specification does not force the browser to follow the value of this attribute; it is a mere hint.

role: Option<AttributeValue<'life>>

Roles define the semantic meaning of content, allowing screen readers and other tools to present and support interaction with an object in a way that is consistent with user expectations of that type of object. roles are added to HTML elements using role="role_type", where role_type is the name of a role in the ARIA specification.

slot: Option<AttributeValue<'life>>

Assigns a slot in a shadow DOM shadow tree to an element: An element with a slot attribute is assigned to the slot created by the <slot> element whose name attribute's value matches that slot attribute's value.

spellcheck: Option<AttributeValue<'life>>

An enumerated attribute defines whether the element may be checked for spelling errors. It may have the following values:

• empty string or true, which indicates that the element should be, if possible, checked for spelling errors;
• false, which indicates that the element should not be checked for spelling errors.

src: Option<AttributeValue<'life>>

The URL of the video to embed. This is optional; you may instead use the <source> element within the video block to specify the video to embed.

style: Option<AttributeValue<'life>>

Contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the <style> element have mainly the purpose of allowing for quick styling, for example for testing purposes.

tabindex: Option<AttributeValue<'life>>

An integer attribute indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can take several values:

• a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation;
• 0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the platform convention;
• a positive value means that the element should be focusable and reachable via sequential keyboard navigation; the order in which the elements are focused is the increasing value of the tabindex. If several elements share the same tabindex, their relative order follows their relative positions in the document.

title: Option<AttributeValue<'life>>

Contains a text representing advisory information related to the element it belongs to. Such information can typically, but not necessarily, be presented to the user as a tooltip.

translate: Option<AttributeValue<'life>>

An enumerated attribute that is used to specify whether an element's attribute values and the values of its Text node children are to be translated when the page is localized, or whether to leave them unchanged. It can have the following values:

• empty string or yes, which indicates that the element will be translated.
• no, which indicates that the element will not be translated.

virtualkeyboardpolicy: Option<AttributeValue<'life>>

An enumerated attribute used to control the on-screen virtual keyboard behavior on devices such as tablets, mobile phones, or other devices where a hardware keyboard may not be available for elements that also uses the contenteditable attribute.

• auto or an empty string, which automatically shows the virtual keyboard when the element is focused or tapped.
• manual, which decouples focus and tap on the element from the virtual keyboard's state.

width: Option<AttributeValue<'life>>

The width of the video's display area, in CSS pixels (absolute values only; no percentages).

Implementations

impl<'life> Video<'life>

pub fn tag() -> &'static str

Get the tag name of the element. This is the same as the name of the struct, in kebab-case.

pub fn set_attr( &mut self, name: &'life str, value: impl Into<AttributeValue<'life>>, )

Sets an attribute of the element. This sets the attribute of the struct. If the attribute is not a known attribute, it is added to the extra map. If the alloc feature is disabled, this function will silently fail.

Note

This only works when the attribute is lowercase.
