Enum bitstream_io::huffman::ReadHuffmanTree

pub enum ReadHuffmanTree<E: Endianness, T: Clone> {
    Done(T, u8, u32, PhantomData<E>),
    Continue(Box<[ReadHuffmanTree<E, T>]>),
    InvalidState,
}

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

InvalidState

An invalid reader state has been used
