Expand description

usize ⇄ f64.

Trait Implementations§

impl<M: Binding<usize> + Copy + 'static> Binding<f64> for Numeric<M>

fn read(&self) -> f64

Tracked read: the current value, subscribing the running computation to changes.

fn peek(&self) -> f64

Untracked read: the current value, subscribing nothing (the reactive world’s “peek”).

fn write(&self, v: f64)

Write the value, waking whatever tracks it.

fn write_preview(&self, v: T)

A live write mid-gesture (Event::ValueChanged): readers must follow, but nothing durable should key off it. Defaults to Binding::write: a plain signal has no notion of “durable”, and a degraded backend that never commits stays correct.

fn write_commit(&self, v: T)

The settled value that ends a gesture (Event::ValueCommitted). Defaults to Binding::write; a day-model field seals its preview session here: one change record, one undo unit, one UPDATE for the whole drag.

fn write_teardown(&self, v: T)

Seal the last preview when its control is disposed. Persistent bindings default to committing; scope-owned signals have already received the preview and may be gone.
