Struct chd::Hunk

pub struct Hunk<'a, F: Read + Seek> { /* private fields */ }

A reference to a compressed Hunk in a CHD file.

Implementations

impl<'a, F: Read + Seek> Hunk<'a, F>

pub fn read_hunk_in( &mut self, compressed_buffer: &mut Vec<u8>, output: &mut [u8] ) -> Result<usize>

Decompresses the hunk into output, using the provided temporary buffer to hold the compressed hunk. The size of the output buffer must be equal to the hunk size of the CHD file.

Returns the number of bytes decompressed on success, which should be the length of the output buffer.

If the hunk refers to a parent CHD that was not provided, this will return Error::RequiresParent.

If the provided output buffer is the wrong length, this will return If the hunk refers to a parent CHD that was not provided, this will return Error::OutOfMemory.

pub fn read_raw_in(&mut self, output: &mut Vec<u8>) -> Result<usize>

Read the raw, compressed contents of the hunk into the provided buffer.

Returns the number of bytes read on success.

pub fn len(&self) -> usize

Returns the length of this hunk in bytes.
