Struct Reader

pub struct Reader<'a, B: BlockDevice> { /* private fields */ }

Implementations

impl<'a, B: BlockDevice> Reader<'a, B>

pub fn cursor(&self) -> usize

pub fn available(&self) -> usize

pub fn volume(&self) -> &Volume<'a, B>

pub fn into_file(self) -> File<'a, B, Unsafe>

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

Similar to ‘File.read’ but does NOT re-read nearby chunks inside the same Block.

This will hold the Cache lock until dropped.
