Trait FileExt 

pub trait FileExt {
    // Required methods
    fn copy_to(&self, to: &File) -> Result<u64>;
    fn update_timestamps(&self) -> Result<()>;
    fn pread_exact(&self, buf: &mut [u8], position: usize) -> Result<()>;
}

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
