Zig allocator backed by [[https://jemalloc.net/][jemalloc]].

* Usage

#+begin_src shell

zig fetch --save=jemalloc https://github.com/jiacai2050/zig-jemalloc/archive/${COMMIT}.tar.gz

#+end_src

Replace ~${COMMIT}~ with a real one, then in your =build.zig=, import the module like this:

#+begin_src zig

const dep_jemalloc = b.dependency("jemalloc", .{});

exe.root_module.addImport("jemalloc", dep_jemalloc.module("jemalloc"));

exe.linkLibC();

#+end_src

This library will link to vendored [[https://github.com/jemalloc/jemalloc/releases/tag/5.3.0][jemalloc(5.3.0)]] by default, you can disable this feature and link to the system-wide version using:

#+begin_src zig

const dep_jemalloc = b.dependency("jemalloc", .{ .link_vendor = false });

// Install jemalloc with system package manager, such as

// brew install jemalloc

// sudo apt-get install libjemalloc-dev

exe.linkSystemLibrary("jemalloc");

exe.linkLibC();

#+end_src

Then in you =main.zig=, initialize like this:

#+begin_src zig

const jemalloc = @import("jemalloc");

const allocator = jemalloc.allocator;

#+end_src
