Required Methods

fn id(&self) -> Id

get the Signal Id

Provided Methods

fn get_untracked(&self) -> T

where T: 'static,

Clones and returns the current value stored in the Signal, but it doesn’t subscribe to the current running effect.

fn get(&self) -> T

where T: 'static,

Clones and returns the current value stored in the Signal, and subscribes to the current running effect to this Signal.

fn try_get(&self) -> Option<T>

where T: 'static,

Try to clone and return the current value stored in the Signal, and returns None if it’s already disposed. It subscribes to the current running effect.

fn try_get_untracked(&self) -> Option<T>

where T: 'static,

Try to clone and return the current value stored in the Signal, and returns None if it’s already disposed. It doesn’t subscribe to the current running effect.
