Required Methods

fn id(&self) -> Id

get the Signal Id

Provided Methods

fn with<O>(&self, f: impl FnOnce(&T) -> O) -> O

where T: 'static,

Applies a closure to the current value stored in the Signal, and subscribes to the current running effect to this Memo.

fn with_untracked<O>(&self, f: impl FnOnce(&T) -> O) -> O

where T: 'static,

Applies a closure to the current value stored in the Signal, but it doesn’t subscribe to the current running effect.

fn try_with<O>(&self, f: impl FnOnce(Option<&T>) -> O) -> O

where T: 'static,

If the signal isn’t disposed, applies a closure to the current value stored in the Signal. It subscribes to the current running effect.

fn try_with_untracked<O>(&self, f: impl FnOnce(Option<&T>) -> O) -> O

where T: 'static,

If the signal isn’t disposed, applies a closure to the current value stored in the Signal, but it doesn’t subscribe to the current running effect.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
