Trait FileReader 

pub trait FileReader {
    // Required method
    fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<usize>;
}

This trait represents file that can atomically be read at specific point

For unix we implement it for File + AsRawFd with pread() system call. For windows we’re implementing it for Mutex<File> and use seek.

Required Methods

fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<usize>

Read file at specified location

This corresponds to the pread system call on most unix systems
