pub struct ChangeOriginProbe<T> { /* private fields */ }

Records values written through a Binding together with their ChangeOrigin.

Implementations

impl<T> ChangeOriginProbe<T>

pub fn new() -> Self

Creates an empty write probe.

impl<T: 'static> ChangeOriginProbe<T>

pub fn binding(&self, read: ReadSignal<T>) -> Binding<T>

Creates a binding whose writes are recorded by this probe.

pub fn binding_with_commit( &self, read: ReadSignal<T>, on_commit: Callback<()>, ) -> Binding<T>

Creates a binding whose writes are recorded and whose commits use on_commit.

impl<T: Debug + PartialEq> ChangeOriginProbe<T>

pub fn assert_writes(&self, expected: &[(T, ChangeOrigin)])

Asserts the complete ordered sequence of value and origin pairs.

Panics

Panics when the observed writes differ from expected.
