Blocking

Struct Blocking 

Source 
pub struct Blocking<'rt, R: ?Sized, W, Out> { /* private fields */ }
Expand description

Payload bound to thread-occupying work.

Implementations§

Source§

impl<'rt, R, W, Out> Blocking<'rt, R, W, Out>
where R: Runtime + ?Sized, Out: Send + 'static, W: FnOnce() -> Result<Out, ProximaError> + Send + 'static,

Source

pub fn spawn(self) -> impl Future<Output = Result<Out, ProximaError>> + Send

Hand the work to the background pool. The Box<dyn Any> round trip the object-safe trait requires is paid here, once, so the caller gets Out.
