Struct miniz_oxide::deflate::core::HuffmanOxide

struct HuffmanOxide {
    pub count: [[u16; 288]; 3],
    pub codes: [[u16; 288]; 3],
    pub code_sizes: [[u8; 288]; 3],
}

A struct containing data about huffman codes and symbol frequencies.

NOTE: Only the literal/lengths have enough symbols to actually use the full array. It’s unclear why it’s defined like this in miniz, it could be for cache/alignment reasons.

Fields

count: [[u16; 288]; 3]

Number of occurrences of each symbol.

codes: [[u16; 288]; 3]

The bits of the huffman code assigned to the symbol

code_sizes: [[u8; 288]; 3]

The length of the huffman code assigned to the symbol.
