Struct File 

#[repr(C)]
pub struct File { /* private fields */ }

Represents an EFI_FILE_PROTOCOL.

Implementations

impl File

pub fn create<N: AsRef<EfiStr>>( &self, name: N, attrs: FileAttributes, ) -> Result<Owned<Self>, FileCreateError>

Creates a file relative to the current file’s location.

This function will create a file if it does not exist, and will truncate it if it does. If the filename starts with a \ the relative location is the root directory that the current file resides on.

pub fn open<N: AsRef<EfiStr>>( &self, name: N, modes: FileModes, attrs: FileAttributes, ) -> Result<Owned<Self>, Status>

Opens a file relative to the current file’s location.

If the filename starts with a \ the relative location is the root directory that the current file resides on.

pub fn read(&mut self, buf: &mut [u8]) -> Result<usize, Status>

Reads data from the file.

pub fn write(&mut self, buf: &[u8]) -> Result<usize, Status>

Writes data to the file.

Partial writes only occur when there has been a data error during the write attempt (such as “file space full”).

pub fn set_position(&mut self, position: u64) -> Result<(), Status>

Sets a file’s current position.

pub fn info(&self) -> Result<Box<FileInfo>, Status>

pub fn set_len(&mut self, len: u64) -> Result<(), FileSetLenError>

pub fn flush(&mut self) -> Result<(), Status>

Flushes all modified data associated with a file to a device.
