§AsyncReadAtManaged
Async read with buffer pool and position
Required Associated Types§
Sourcetype BufferPool
type BufferPool
Buffer pool type
Required Methods§
Sourceasync fn read_managed_at(
&self,
pos: u64,
buffer_pool: &Self::BufferPool,
len: usize,
) -> Result<Self::Buffer>
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.
