Trait MetastackExt 

pub trait MetastackExt<'s>: Sized {
    type Output;

    // Required methods
    fn with_metastack_resume_point(
        self,
    ) -> Pin<Box<dyn Future<Output = Self::Output> + 's>>;

Required Associated Types

type Output

Required Methods

fn with_metastack_resume_point( self, ) -> Pin<Box<dyn Future<Output = Self::Output> + 's>>

Transforms a future into a future that will return Poll::Pending if there is not enough stack space to execute the future.

fn run_sync_with_metastack(self) -> Self::Output

Sets up a landing pad to catch Poll::Pending returns and run the next scheduled future on a slightly emptier stack.

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.
