Trait AsyncReadAt

pub trait AsyncReadAt {
    // Required method
    async fn read_at<T: IoBufMut>(
        &self,
        buf: T,
        pos: u64,
    ) -> BufResult<usize, T>;

    // Provided method
    async fn read_vectored_at<T: IoVectoredBufMut>(
        &self,
        buf: T,
        pos: u64,
    ) -> BufResult<usize, T> { ... }
}

AsyncReadAt

Async read with a ownership of a buffer and a position

Required Methods

async fn read_at<T: IoBufMut>(&self, buf: T, pos: u64) -> BufResult<usize, T>

Like AsyncRead::read, except that it reads at a specified position.

Provided Methods

async fn read_vectored_at<T: IoVectoredBufMut>( &self, buf: T, pos: u64, ) -> BufResult<usize, T>

Like AsyncRead::read_vectored, except that it reads at a specified position.

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.
