Trait photonio_base::io::ReadAt

pub trait ReadAt {
    type ReadAt<'a>: Future<Output = Result<usize>> + 'a
    where
        Self: 'a;

    fn read_at<'a>(&'a self, buf: &'a mut [u8], pos: u64) -> Self::ReadAt<'a>;
}

Reads some bytes from an object at a given position.

Required Associated Types

type ReadAt<'a>: Future<Output = Result<usize>> + 'a
where
    Self: 'a

A future that resolves to the result of Self::read_at.

Required Methods
