Enum Oco 

pub enum Oco<'a, T>
where
    T: ToOwned + 'a + ?Sized,
{
    Borrowed(&'a T),
    Counted(Arc<T>),
    Owned(<T as ToOwned>::Owned),
}

“Owned Clones Once”: a smart pointer that can be either a reference, an owned value, or a reference-counted pointer. This is useful for storing immutable values, such as strings, in a way that is cheap to clone and pass around.

The cost of the Clone implementation depends on the branch. Cloning the Oco::Borrowed variant simply copies the references (O(1)). Cloning the Oco::Counted variant increments a reference count (O(1)). Cloning the Oco::Owned variant requires an O(n) clone of the data.

For an amortized O(1) clone, you can use Oco::clone_inplace(). Using this method, Oco::Borrowed and Oco::Counted are still O(1). Oco::Owned does a single O(n) clone, but converts the object to the Oco::Counted branch, which means future clones will be O(1).

In general, you’ll either want to call clone_inplace() once, before sharing the Oco with other parts of your application (so that all future clones are O(1)), or simply use this as if it is a Cow with an additional branch for reference-counted values.

Variants

Borrowed(&'a T)

A static reference to a value.

Counted(Arc<T>)

A reference counted pointer to a value.

Owned(<T as ToOwned>::Owned)

The type once all async data have loaded.

type State = (Element, Oco<'static, str>)

The state that should be retained between building and rebuilding.

type Cloneable = Oco<'static, str>

A version of the value that can be cloned. This can be the same type, or a reference-counted type. Generally speaking, this does not need to refer to the same data, but should behave in the same way. So for example, making an event handler cloneable should probably make it reference-counted (so that a FnMut() continues mutating the same closure), but making a String cloneable does not necessarily need to make it an Arc<str>, as two different clones of a String will still have the same value.

type CloneableOwned = Oco<'static, str>

A cloneable type that is also 'static. This is used for spreading across types when the spreadable attribute needs to be owned. In some cases (&'a str to Arc<str>, etc.) the owned cloneable type has worse performance than the cloneable type, so they are separate.

Renders a view to HTML, writing it into the given buffer.

fn hydrate<const FROM_SERVER: bool>( self, cursor: &Cursor, position: &PositionState, ) -> <Oco<'static, str> as Render>::State

Makes a set of DOM nodes rendered from HTML interactive.

fn into_owned(self) -> <Oco<'static, str> as RenderHtml>::Owned

Convert into the equivalent value that is 'static.

const EXISTS: bool = true

Whether this should actually exist in the DOM, if it is the child of an element.

fn html_len(&self) -> usize

An estimated length for this view, when rendered to HTML.

fn to_html(self) -> String

where Self: Sized,

Renders a view to an HTML string.

fn to_html_branching(self) -> String

where Self: Sized,

Renders a view to HTML with branch markers. This can be used to support libraries that diff HTML pages against one another, by marking sections of the view that branch to different types with marker comments.

fn to_html_stream_in_order(self) -> StreamBuilder

where Self: Sized,

Renders a view to an in-order stream of HTML.

fn to_html_stream_in_order_branching(self) -> StreamBuilder

where Self: Sized,

Renders a view to an in-order stream of HTML with branch markers. This can be used to support libraries that diff HTML pages against one another, by marking sections of the view that branch to different types with marker comments.

fn to_html_stream_out_of_order(self) -> StreamBuilder

where Self: Sized,

Renders a view to an out-of-order stream of HTML.

fn to_html_stream_out_of_order_branching(self) -> StreamBuilder

where Self: Sized,

Renders a view to an out-of-order stream of HTML with branch markers. This can be used to support libraries that diff HTML pages against one another, by marking sections of the view that branch to different types with marker comments.

fn to_html_async_with_buf<const OUT_OF_ORDER: bool>( self, buf: &mut StreamBuilder, position: &mut Position, escape: bool, mark_branches: bool, extra_attrs: Vec<AnyAttribute>, )

where Self: Sized,

Renders a view into a buffer of (synchronous or asynchronous) HTML chunks.

fn hydrate_async( self, cursor: &Cursor, position: &PositionState, ) -> impl Future<Output = Self::State>

Asynchronously makes a set of DOM nodes rendered from HTML interactive.

fn hydrate_from<const FROM_SERVER: bool>(self, el: &Element) -> Self::State

where Self: Sized,

Hydrates using RenderHtml::hydrate, beginning at the given element.

fn hydrate_from_position<const FROM_SERVER: bool>( self, el: &Element, position: Position, ) -> Self::State

where Self: Sized,

Hydrates using RenderHtml::hydrate, beginning at the given element and position.

impl<'a, T> Serialize for Oco<'a, T>

where T: ToOwned + 'a + ?Sized, &'b T: for<'b> Serialize,

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl ToTemplate for Oco<'static, str>

const TEMPLATE: &'static str = <&str as ToTemplate>::TEMPLATE

The HTML content of the static template.

fn to_template( buf: &mut String, class: &mut String, style: &mut String, inner_html: &mut String, position: &mut Position, )

Renders a view type to a template. This does not take actual view data, but can be used for constructing part of an HTML <template> that corresponds to a view of a particular type.

const CLASS: &'static str = ""

The class attribute content known at compile time.

const STYLE: &'static str = ""

The style attribute content known at compile time.

const LEN: usize = _

The length of the template.

fn to_template_attribute( buf: &mut String, class: &mut String, style: &mut String, inner_html: &mut String, position: &mut Position, )

Renders a view type to a template in attribute position.

impl<T> Eq for Oco<'_, T>

where T: ToOwned + Eq + ?Sized,
