Trait AsyncReadManaged 

pub trait AsyncReadManaged {
    type BufferPool;
    type Buffer<'a>;

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

Available on crate feature io only.

AsyncReadManaged

Async read with buffer pool

Required Associated Types

type BufferPool

Buffer pool type

type Buffer<'a>

Filled buffer type

Required Methods

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

Read some bytes from this source with Self::BufferPool and return a Self::Buffer.

If len == 0, will use Self::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.
