Fields

min_code: [i32; 17]

Smallest code for each code length; i32::MAX when absent.

max_code: [i32; 17]

Largest code for each code length; -1 when absent.

val_offset: [i32; 17]

Value-index offset for each code length.

huffcode: [u16; 256]

Canonical Huffman code for each value index.

huffsize: [u8; 256]

Canonical Huffman code length for each value index.

huffsize_len: usize

Number of valid entries in huffcode and huffsize.
