libzstd

libzstd is a Zig package that vendors C compression libraries and exposes small typed Zig wrappers.

Current status:

• libzstd: implemented (source is compiled by Zig)
• libbrotli: planned
• libdeflate: planned

Features

• Compiles upstream libzstd sources directly in build.zig
• Exposes one-shot and streaming APIs in Zig (std.Io.Reader / std.Io.Writer)
• Exposes full raw libzstd API under libzstd.c
• Supports both libc modes:
  • static libc via ziglibc (default)
  • dynamic/system libc via -Dstatic_libc=false

Build Options

• -Dstatic_libc=true|false (default true): static ziglibc or system libc
• -Dshared=true|false (default false): build libzstd artifact as shared/static

Commands

zig build test
zig build test -Dstatic_libc=false
zig build example

Zig API

const zstd = @import("libzstd");

const compressed = try zstd.compressDefault(allocator, input);
defer allocator.free(compressed);

const decompressed = try zstd.decompress(allocator, compressed, input.len * 2);
defer allocator.free(decompressed);

Raw libzstd symbols are exposed through zstd.c, e.g. zstd.c.ZSTD_versionNumber().
