Enum bitstream_io::huffman::ReadHuffmanTree [−][src]
pub enum ReadHuffmanTree<E: Endianness, T: Clone> { Done(T, u8, u32, PhantomData<E>), Continue(Box<[ReadHuffmanTree<E, T>]>), InvalidState, }
Expand description
A compiled Huffman tree element for use with the read_huffman method.
Returned by compile_read_tree.
Compiled read trees are optimized for faster lookup and are therefore endian-specific.
In addition, each symbol in the source tree may occur many times in the compiled tree. If symbols require a nontrivial amount of space, consider using reference counting so that they may be cloned more efficiently.
Variants
Done(T, u8, u32, PhantomData<E>)The final value and new reader state
Continue(Box<[ReadHuffmanTree<E, T>]>)Another byte is necessary to determine final value
An invalid reader state has been used
