A generic file trait.

Required methods

source

fn id(&self) -> Option<u64>

Returns the unique ID of this file. Only unique within the manager it was opened from.

source

fn path(&self) -> &Path

Returns the path to the file.

source

fn length(&self) -> Result<u64, Error>

Returns the length of the file.

source

fn synchronize(&mut self) -> Result<(), Error>

Synchronizes data and metadata to the final destination. This calls std::fs::File::sync_all() on files, which ensures all filesystem metadata (such as newly allocated blocks) and data is synchronized to the destination device.
