Tracking Issue for seek_read_exact_seek_write_all #162868
Description
Feature gate: #![feature(seek_read_exact_seek_write_all)]
This is a tracking issue for seek_read_exact_seek_write_all
Add .seek_read_exact(), .seek_write_all() methods to std::os::windows::fs::FileExt to complement the .read_exact_at(), .write_all_at() methods in std::os::unix::fs::FileExt.
And add seek_read_buf_exact() to complement read_buf_exact_at().
Public API
// std::os::windows::fs
pub trait FileExt {
fn seek_read_exact(&self, mut buf: &mut [u8], mut offset: u64) -> io::Result<()>;
fn seek_read_buf_exact(
&self,
mut buf: BorrowedCursor<'_, u8>,
mut offset: u64,
) -> io::Result<()>;
fn seek_write_all(&self, mut buf: &[u8], mut offset: u64) -> io::Result<()>;
