Struct cloudflare_zlib::Deflate

pub struct Deflate { /* fields omitted */ }

Implementations

impl Deflate

Compress

pub fn new_default() -> Result<Self, ZError>

pub fn new(
    level: c_int,
    strategy: c_int,
    window_bits: c_int
) -> Result<Self, ZError>

Use zlib's magic constants:

• level = Z_BEST_SPEED (1) to Z_BEST_COMPRESSION (9)
• strategy = Z_DEFAULT_STRATEGY, Z_FILTERED, Z_HUFFMAN_ONLY, Z_RLE, Z_FIXED
• window_bits = 15

pub fn new_with_vec(
    level: c_int,
    strategy: c_int,
    window_bits: c_int,
    buf: Vec<u8>
) -> Result<Self, ZError>

Same as new, but can append to any Vec

pub fn reserve(&mut self, compressed_size: usize)

Expect (remaining) data to take this much space after compression

pub fn compress(&mut self, data: &[u8]) -> Result<(), ZError>

Add bytes from data to compressed data

pub fn compress_with_limit(
    &mut self,
    data: &[u8],
    max_size: &AtomicUsize
) -> Result<(), ZError>

dd bytes from data to compressed data, unless the total compressed output would exceed max_size

pub fn finish(self) -> Result<Vec<u8>, ZError>
