Struct MetaAttributes

pub struct MetaAttributes {
    pub name: Option<String>,
    pub http_equiv: Option<String>,
    pub content: String,
}

The metadata and meta elements are containers in which information about the document can be placed. The metadata element provides more general and powerful treatment of metadata information than meta by using a metadata schema.

A meta declaration associates a string to a declared meta property or declares “http-equiv” content. Either a name or http-equiv attribute is REQUIRED. It is an error to provide both name and http-equiv attributes. A content attribute is REQUIRED. The seeAlso property is the only defined meta property name. It is used to specify a resource that might provide additional metadata information about the content. This property is modeled on the seeAlso property of Resource Description Framework (RDF) Schema Specification 1.0 [RDF-SCHEMA §5.4.1]. The http-equiv attribute has a special significance when documents are retrieved via HTTP. Although the preferred method of providing HTTP header information is by using HTTP header fields, the “http-equiv” content MAY be used in situations where the SSML document author is unable to configure HTTP header fields associated with their document on the origin server, for example, cache control information. Note that HTTP servers and caches are not required to introspect the contents of meta in SSML documents and thereby override the header values they would send otherwise.

Fields

name: Option<String>

Currently, the only defined name is seeAlso. In future other meta names may be added.

http_equiv: Option<String>

Used for when documents are retrieved via HTTP.

content: String

The content referred to by the meta.

Trait Implementations

impl Clone for MetaAttributes

fn clone(&self) -> MetaAttributes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MetaAttributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MetaAttributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MetaAttributes

fn eq(&self, other: &MetaAttributes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
