Crate east

Non keyed iteration (or keyed by index). Use this instead of directly rendering an array of Views. Using this will minimize re-renders instead of re-rendering every single node on every state change.

Keyed

Keyed iteration. Use this instead of directly rendering an array of Views. Using this will minimize re-renders instead of re-rendering every view node on every state change.

create_child_scope

Create a child scope.

create_effect

Creates an effect on signals used inside the effect closure.

create_effect_scoped

Creates an effect on signals used inside the effect closure.

create_memo

Creates a memoized computation from some signals. The output is derived from all the signals that are used within the memo closure. If any of the tracked signals are updated, the memo is also updated.

create_node_ref

Create a new NodeRef on the current Scope.

create_rc_signal

Create a new RcSignal with the specified initial value.

create_rc_signal_from_rc

Create a new RcSignal with the specified initial value wrapped in a Rc.

create_reducer

An alternative to create_signal that uses a reducer to get the next value.

create_ref

Allocate a new arbitrary value under the current Scope. The allocated value lasts as long as the scope and cannot be used outside of the scope.

create_scope

Creates a reactive scope.

create_scope_immediate

Creates a reactive scope, runs the callback, and disposes the scope immediately.

create_selector

Creates a memoized value from some signals. Unlike create_memo, this function will not notify dependents of a change if the output is the same. That is why the output of the function must implement PartialEq.

create_selector_with

Creates a memoized value from some signals. Unlike create_memo, this function will not notify dependents of a change if the output is the same.

create_signal

Create a new Signal under the current Scope. The created signal lasts as long as the scope and cannot be used outside of the scope.

create_signal_from_rc

Create a new Signal under the current Scope but with an initial value wrapped in a Rc. This is useful to avoid having to clone a value that is already wrapped in a Rc when creating a new signal. Otherwise, this is identical to create_signal.

escape

Escape HTML string.

escape_to_string

Escape HTML string to output.

json_to_string

Serialize the given data structure as a String of JSON.

map_indexed

Function that maps a Vec to another Vec via a map function. The mapped Vec is lazy computed, meaning that it’s value will only be updated when requested. Modifications to the input Vec are diffed by index to prevent recomputing values that have not changed.

map_keyed

Function that maps a Vec to another Vec via a map function. The mapped Vec is lazy computed, meaning that it’s value will only be updated when requested. Modifications to the input Vec are diffed using keys to prevent recomputing values that have not changed.

on

A helper function for making it explicit to define dependencies for an effect.

on_cleanup

Adds a callback that is called when the scope is destroyed.

on_mount

Queue up a callback to be executed when the component is mounted.

provide_context

Provides a context in the current Scope. The context can later be accessed by using use_context lower in the scope hierarchy.

provide_context_ref

Provides a context in the current Scope. The context can later be accessed by using use_context lower in the scope hierarchy.

render_to_string

Render a View into a static String. Useful for rendering to a string on the server side.
