The deflate package is a translation of the Go code of the compress/flate package from https://go.googlesource.com/go/+/refs/tags/go1.17/src/compress/flate/

 

const deflate = @import("deflate/compressor.zig");
const inflate = @import("deflate/decompressor.zig");

pub const Compression = deflate.Compression;

CompressorOptions

 
pub const CompressorOptions = deflate.CompressorOptions;

copy()

Copies elements from a source src slice into a destination dst slice. The copy never returns an error but might not be complete if the destination is too small. Returns the number of elements copied, which will be the minimum of src.len and dst.len. TODO: remove this smelly function

 
pub fn copy(dst: []u8, src: []const u8) usize {
    if (dst.len <= src.len) {
        @memcpy(dst, src[0..dst.len]);
        return dst.len;
    } else {
        @memcpy(dst[0..src.len], src);
        return src.len;
    }
}
