Trait ReadAtAsync

pub trait ReadAtAsync {
    // Required method
    fn read_at<B>(&self, buf: B, offset: u64) -> impl Future<Output = Result<B>>
       where AsyncReadBytes<B>: From<B>,
             B: AsMut<[u8]> + Unpin + 'static;

    // Provided method
    fn offset(&self, offset: u64) -> ReadAtOffset<'_, Self>
       where Self: Sized { ... }
}

Async version of ReadAt, it is neither Send nor Sync and is supposed to be used with concurrent async combinators

Required Methods

fn read_at<B>(&self, buf: B, offset: u64) -> impl Future<Output = Result<B>>

where AsyncReadBytes<B>: From<B>, B: AsMut<[u8]> + Unpin + 'static,

Fill the buffer by reading bytes at a specific offset and return the buffer back

Provided Methods

fn offset(&self, offset: u64) -> ReadAtOffset<'_, Self>

where Self: Sized,

Get implementation of ReadAtAsync that add specified offset to all attempted reads

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.
