Struct FocusExitOrderProbe 

pub struct FocusExitOrderProbe { /* private fields */ }

Records the relative order of binding writes, Commits, and Focus Exits.

This optional probe creates a Binding for a registry adapter to drive through its normal interaction path. Its write callback records the event but deliberately owns no value state; use ChangeOriginProbe separately when the test also needs to assert values and origins.

Implementations

impl FocusExitOrderProbe

pub fn new() -> Self

Creates an empty Focus Exit order probe.

pub fn binding<T: 'static>(&self, read: ReadSignal<T>) -> Binding<T>

pub fn assert_commit_without_focus_exit(&self)

Asserts that one Commit occurred without a Focus Exit.

Panics when Commit was omitted or repeated, or any write or Focus Exit was observed.

pub fn assert_write_and_commit_before_focus_exit(&self)

Asserts that one synchronous write and Commit were observed before one Focus Exit.

Panics

Panics when an event was omitted, repeated, or observed out of order.
