Trait FileExt

Helper functions for std::fs::File

Required Methods

fn copy_to(&self, to: &File) -> Result<u64>

👎Deprecated: Use std::io::copy instead

Copy the entire contents of self to to. This uses operating system specific fast paths if available.

fn update_timestamps(&self) -> Result<()>

Update timestamps (both access and modification) to the current time.

fn pread_exact(&self, buf: &mut [u8], position: usize) -> Result<()>

Read the exact number of bytes required to fill buf starting from position, without affecting file offset.
