Trait AsyncReadManaged

pub trait AsyncReadManaged {
    type BufferPool;
    type Buffer: IoBuf;

    // Required method
    async fn read_managed(
        &mut self,
        buffer_pool: &Self::BufferPool,
        len: usize,
    ) -> Result<Self::Buffer>;
}

AsyncReadManaged

Async read with buffer pool

Required Associated Types

type BufferPool

Buffer pool type

type Buffer: IoBuf

Filled buffer type

Required Methods

async fn read_managed( &mut self, buffer_pool: &Self::BufferPool, len: usize, ) -> Result<Self::Buffer>

Read some bytes from this source with [BufferPool] and return a [Buffer].

If len == 0, will use [BufferPool] inner buffer size as the max len, if len > 0, min(len, inner buffer size) will be the read max len

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.
