Struct Effect 

pub struct Effect { /* private fields */ }

A live subscription. Dropping it deregisters the effect, so the closure runs once and never again — which looks exactly like a working binding until the value it derives is expected to move. Bind it to something that lives as long as the work should: a struct field, a returned value, or a let the reader captures.

Trait Implementations

impl Drop for Effect

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
