Fields

state: State

Current state of the decompressor.

num_bits: u32

Number of bits in the bit buffer.

z_header0: u32

Zlib CMF

z_header1: u32

Zlib FLG

z_adler32: u32

Adler32 checksum from the zlib header.

finish: u8

1 if the current block is the last block, 0 otherwise.

block_type: u8

The type of the current block. or if in a dynamic block, which huffman table we are currently

check_adler32: u32

1 if the adler32 value should be checked.

dist: u32

Last match distance.

counter: u32

Variable used for match length, symbols, and a number of other things.

num_extra: u8

Number of extra bits for the last length or distance code.

table_sizes: [u16; 3]

Number of entries in each huffman table.

bit_buf: u64

Buffer of input data.

tables: [HuffmanTable; 3]

Huffman tables.

code_size_literal: [u8; 288]

code_size_dist: [u8; 32]

code_size_huffman: [u8; 19]

raw_header: [u8; 4]

Raw block header.

len_codes: [u8; 512]

Huffman length codes.

Implementations

impl DecompressorOxide

pub fn new() -> DecompressorOxide

Create a new tinfl_decompressor with all fields set to 0.

pub fn init(&mut self)

Set the current state to Start.

pub fn adler32(&self) -> Option<u32>

Returns the adler32 checksum of the currently decompressed data. Note: Will return Some(1) if decompressing zlib but ignoring adler32.

pub fn adler32_header(&self) -> Option<u32>

Returns the adler32 that was read from the zlib header if it exists.

Trait Implementations

impl Clone for DecompressorOxide

fn clone(&self) -> DecompressorOxide

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for DecompressorOxide

fn default() -> Self

Create a new tinfl_decompressor with all fields set to 0.
