Crate egui_reactor 

Core of egui-reactor: View, Cx, Store, State, Handle, Dispatch, the hooks and the layout and paint attribute types.

rsx!, #[component] and #[hook] come from egui-reactor-macros and are re-exported here, so use egui_reactor::prelude::* is the only import a component file needs.

Re-exports

pub use layout::Align;

pub use layout::AlignSelf;

pub use layout::ContainerStyle;

pub use layout::Display;

pub use layout::Gap;

pub use taffy;

Modules

layout

Layout attributes: Length, ItemStyle and ContainerStyle.

paint

Paint attributes: PaintStyle, the look of a box.

prelude

Everything a component needs, in one use.

Macros

rsx

Build a View from JSX-like syntax.

Structs

Arity0

Marker: the handler ignores the payload (|| ..).

Arity1

Marker: the handler takes the payload (|payload| ..).

Collision

A hook id that was requested twice within one pass.

Cx

The context passed to components and hooks.

Dispatch

A Clone + Send sender into one use_reducer’s message queue.

Emitter

A child-side handle that fires one event kind.

FnCleanup

Marker for an effect body that returns a cleanup closure.

Handle

A Copy accessor to one hook slot.

NoCleanup

Marker for an effect body that returns no cleanup.

State

A guard over one use_state slot.

Store

Owns every hook’s state, keyed by [egui::Id].

Traits

Handler

A callback prop that may or may not take the event payload.

IntoCleanup

What an effect body may return.

Props

Implemented by every #[component] props struct.

SpawnFuture

A future use_future and spawn can run.

View

Something that can draw itself into a Cx.

Functions

props_builder

Get the props builder for a component function.

provide_context

Make value visible to use_context::<T> inside children.

spawn

Run a future to completion and throw its result away.

use_animate

egui’s animate_bool_with_time_and_easing behind a hook: 0 while on is false, 1 while it is true, and in between for time seconds after on flips, eased with cubic_out.

use_animate_with

use_animate with an easing of the caller’s choosing (egui::emath::easing).

use_context

Read the innermost Handle provided for T, if any.

use_effect

Run f on the first visit and whenever the hash of deps changes.

use_future

Run the future f builds, and report where it has got to.

use_handle

Like use_state, but returns a Copy Handle instead of a guard.

use_memo

Compute f on the first visit and whenever the hash of deps changes.

use_persisted

Hold T in the store and in the app’s storage, keyed by key.

use_reducer

Hold S in the store and fold queued messages into it with reducer.

use_state

Hold T in the store, initialising it on the first visit.

view

Wrap a closure as a View, fixing the closure’s argument type.

Type Aliases

EventSink

The fused event closure a parent hands to a child, shared by every emitter.

Attribute Macros

component

Turn a function into a egui-reactor component.

hook

Turn a function into a custom hook.
