Trait BlockOn

pub trait BlockOn:
    Clone
    + Send
    + Sync
    + 'static {
    // Required method
    fn block_on<F: Future>(&self, future: F) -> F::Output;
}

Trait for a runtime that can block on a future.

Required Methods

fn block_on<F: Future>(&self, future: F) -> F::Output

Run future until it is ready, and return its output.

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.
