uuid.zigUUID Library for Zig

Production-ready, high-performance UUID generation, parsing, and formatting for Zig 0.16.0.

All UUID Versions

Full support for v1 (time-based), v3 (MD5), v4 (random), v5 (SHA-1), v6 (reordered time), v7 (epoch time), and v8 (application-specific).

Generate, parse, format, and compare UUIDs without any heap allocation. Only the Generator type uses an allocator for string conversion.

Parse UUIDs in canonical, compact, braced, and URN formats with comprehensive error detection for invalid characters, lengths, and formats.

Format UUIDs as canonical, uppercase, compact, braced, or URN strings. All formatters write to caller-provided buffers.

v4 and v7 UUIDs use std.Io.randomSecure for cryptographically secure random bytes.

v3 and v5 UUIDs are deterministic given the same namespace and name. Custom timestamps enable reproducible testing.
