Required Methods§

Source

fn read( &self, offset: u64, n: usize, result: *mut Slice, scratch: *mut u8, ) -> Status

| Read up to “n” bytes from the file starting | at “offset”. “scratch[0..n-1]” may be | written by this routine. Sets “*result” to | the data that was read (including if fewer | than “n” bytes were successfully read). May | set “*result” to point at data in | “scratch[0..n-1]”, so “scratch[0..n-1]” must | be live when “*result” is used. If an error | was encountered, returns a non-OK status. | | Safe for concurrent use by multiple threads.
