    },
}

Extra input data passed alongside an action dispatch.

When the platform delivers an effect result or a drag-and-drop event, it attaches an ActionInput so the reducer can access the associated data without encoding it in the action payload.

Example

fn on_file_loaded(
    state: &mut MyState,
    _action: FileLoaded,
    ctx: &mut ReducerContext<MyState>,
) {
    if let Some(bytes) = ctx.input.as_bytes() {
        state.file_contents = String::from_utf8_lossy(bytes).into_owned();
    }
}

Trait Implementations

impl Clone for ActionInput

fn clone(&self) -> ActionInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActionInput

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

Formats the value using the given formatter.

impl PartialEq for ActionInput

fn eq(&self, other: &ActionInput) -> 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.
