Expand description
Adds the ability to scope task-local data for !Send futures
Required Methods§
Sourcefn scope_local<F, R>(
locals: TaskLocals,
fut: F,
) -> Pin<Box<dyn Future<Output = R>>>where
F: Future<Output = R> + 'static,
fn scope_local<F, R>(
locals: TaskLocals,
fut: F,
) -> Pin<Box<dyn Future<Output = R>>>where
F: Future<Output = R> + 'static,
Set the task locals for the given !Send future
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.
