Trait ThreadPool

    + Sync
    + RefUnwindSafe

    + Unpin {
    // Required methods
    fn threads(&self) -> usize;

             Fut: Future<Output = T> + 'a,
             T: Send + 'a;

    // Provided method
    fn spawn<F, Fut, T>(
        &self,
        work: F,
    ) -> BoxFuture<'static, Result<T, Box<dyn Error + Send>>>

             Fut: Future<Output = T> + 'static,

}

Required Methods

fn threads(&self) -> usize

unsafe fn spawn_unchecked<'a, F, Fut, T>( &self, work: F, ) -> BoxFuture<'a, Result<T, Box<dyn Error + Send>>>

where F: FnOnce() -> Fut + Send + 'a, Fut: Future<Output = T> + 'a, T: Send + 'a,

Safety

Must be polled to completion before dropping. Unsound to forget it without having polled to completion.

Provided Methods

fn spawn<F, Fut, T>( &self, work: F, ) -> BoxFuture<'static, Result<T, Box<dyn Error + Send>>>

where F: FnOnce() -> Fut + Send + 'static, Fut: Future<Output = T> + 'static, T: Send + 'static,

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.
