compress.gzip #

Description

compress.gzip is a module that assists in the compression and decompression of binary data using gzip compression

Examples:

import compress.gzip

fn main() {
    uncompressed := 'Hello world!'
    compressed := gzip.compress(uncompressed.bytes())!
    decompressed := gzip.decompress(compressed)!
    assert decompressed == uncompressed.bytes()
}

fn compress(data []u8) ![]u8

compresses an array of bytes using gzip and returns the compressed bytes in a new array

compressed := gzip.compress(b)!

fn decompress(data []u8, params DecompressParams) ![]u8

decompresses an array of bytes using zlib and returns the decompressed bytes in a new array

decompressed := gzip.decompress(b)!

fn validate(data []u8, params DecompressParams) !GzipHeader

validate validates the header and returns its details if valid

struct DecompressParams {
pub:
	verify_header_checksum bool = true
	verify_length          bool = true
	verify_checksum        bool = true
}

struct GzipHeader {
pub mut:
	length            int = 10
	extra             []u8
	filename          []u8
	comment           []u8
	modification_time u32
	operating_system  u8
}
