Trait Buffers 

pub trait Buffers<T>
where
    T: ?Sized,
{
    type Buffer<'a>: DerefMut<Target = T>
       where Self: 'a;

    // Required methods
    async fn get(&self) -> Option<Self::Buffer<'_>>;
    fn get_immediate(&self) -> Option<Self::Buffer<'_>>;
}

A trait for getting access to a &mut T buffer, potentially awaiting until a buffer becomes available.

Required Associated Types

type Buffer<'a>: DerefMut<Target = T> where Self: 'a

Required Methods

async fn get(&self) -> Option<Self::Buffer<'_>>

Get a reference to a buffer. Might await until a buffer is available, as it might be in use by somebody else.

Depending on its internal implementation details, access to a buffer might also be denied immediately, or after a certain amount of time (subject to the concrete implementation of the method). In that case, the method will return None.

fn get_immediate(&self) -> Option<Self::Buffer<'_>>

Get a reference to a buffer immediately, without waiting. If no buffer is available, return None.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<B, T> Buffers<T> for &B

where B: Buffers<T>, T: ?Sized,

type Buffer<'a> = <B as Buffers<T>>::Buffer<'a> where &B: 'a

fn get(&self) -> impl Future<Output = Option<<&B as Buffers<T>>::Buffer<'_>>>

fn get_immediate(&self) -> Option<<&B as Buffers<T>>::Buffer<'_>>
