impl Inflate

fn total_in(&self) -> u64

The amount of bytes consumed from the input so far.

fn total_out(&self) -> u64

The amount of decompressed bytes that have been written to the output thus far.

fn error_message(&self) -> Option<&'static str>

The error message if the previous operation failed.

fn new(expect_header: bool, window_bits: u8) -> Self

Create a new instance. This function allocates, and so it is recommended to re-use this state when possible, using Inflate::reset as needed.

This function will:

• decode a raw deflate stream when expect_header = false and window_bits is in the range 8..=15
• decode a zlib header followed by a deflate stream when expect_header = true and window_bits is in the range 8..=15
• decode a gzip header followed by a deflate stream when expect_header = true and window_bits is in the range 16 + 8..=16 + 15
• decode either a zlib or a gzip header, followed by a deflate stream when expect_header = true and window_bits is in the range 32 + 8..=32 + 15

window_bits can also be 0 to request that inflate use the window size in the zlib header of the compressed stream when using zlib.

Note that when deflating a value of window_bits = 8 is silently converted to window_bits = 9 in most zlib implementations, and hence should be inflated using window_bits = 9.

Panics

This function may panic when the window_bits and expect_header have values not listed above.

fn reset(&mut self, zlib_header: bool)

Reset the state to allow handling a new stream.

fn decompress(&mut self, input: &[u8], output: &mut [u8], flush: InflateFlush) -> Result<Status, InflateError>

Decompress input and write all decompressed bytes into output, with flush defining some details about this.

fn decompress_uninit(&mut self, input: &[u8], output: &mut [MaybeUninit<u8>], flush: InflateFlush) -> Result<Status, InflateError>

Decompress input and write all decompressed bytes into a potentially uninitialized output, with flush defining some details about this.

fn set_dictionary(&mut self, dictionary: &[u8]) -> Result<u32, InflateError>
