Expand description

§AsyncReadAtManaged

Async read with buffer pool and position

Required Associated Types§

Source

type BufferPool

Buffer pool type

Source

type Buffer: IoBuf

Filled buffer type

Required Methods§

Source

async fn read_managed_at( &self, pos: u64, buffer_pool: &Self::BufferPool, len: usize, ) -> Result<Self::Buffer>

Read some bytes from this source at position 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.
