quiche-zig

Zig bindings to quiche — Cloudflare's QUIC + HTTP/3 implementation. A single quiche module exposes both quiche's C API and the bundled BoringSSL headers (SSL_*, EVP_*, ...). The static library contains BoringSSL inlined, so no separate ssl/crypto link step is needed.

Currently builds quiche 0.30.0 from the upstream crate, using its locked boring-sys 5.2.0 dependency for BoringSSL. The Zig dependency on boring-sys supplies matching C headers and must track quiche's Cargo.lock.

Requirements

• Zig 0.16+
• Rust 1.88+ (cargo) on PATH, CMake 3.22+, and libclang for BoringSSL's Rust bindings. For cross-compiling, install the matching rustup target.

The build uses Zig's C/C++ compiler and linker for BoringSSL and Cargo, including cross-compilation, so they share the same C++ runtime as the consuming Zig code.

Use

In your build.zig:

const dep = b.dependency("quiche", .{ .target = target, .optimize = optimize });
exe.root_module.addImport("quiche", dep.module("quiche"));

In Zig source:

const std = @import("std");
const quiche = @import("quiche");

pub fn main() void {
    std.debug.print("quiche {s}\n", .{quiche.quiche_version()});
}
