Struct File 

pub struct File { /* private fields */ }

A read view of a file.

Can be used to recover data, or convert into a Writer.

Implementations

impl File

pub fn new<T: AsRawFd>(fd: T) -> Result<Self, Error>

pub fn recover(&self, cfg: &mut ConfigureFile) -> Option<FileDiscovery<'_>>

Attempt to recover the configuration from existing data.

This method writes the read information into the output argument cfg and returns a proxy with the recovered configuration. The proxy can be used to partially access the contained entries as well, if the discovery succeeded.

pub fn configure(self, cfg: &ConfigureFile) -> Writer

Change the metadata of the file, to the one described in the configuration.

pub fn into_writer_unguarded(self) -> Writer

Convert this into a writer, without minding data consistency.
