fastfilter

Binary fuse & xor filters for Zig (faster and smaller than bloom filters)

GitHub repository | Issue tracker

Getting started

Create a build.zig.zon in your project (replace LATEST_COMMIT with the latest commit hash):

.{
    .name = "mypkg",
    .version = "0.1.0",
    .dependencies = .{
        .fastfilter = .{
            .url = "https://pkg.machengine.org/fastfilter/LATEST_COMMIT.tar.gz",
        },
    },
}

Run zig build in your project, and the compiler will instruct you to add a .hash = "..." field next to .url:

note: expected .hash = "12209838fcfb7a77d2d6931efdc7448c033a1b7dad11d082c94bbeeba9d1038cd311",

Then use the dependency in your build.zig:

pub fn build(b: *std.Build) void {
    ...
    exe.addModule("fastfilter", b.dependency("fastfilter", .{
        .target = target,
        .optimize = optimize,
    }).module("fastfilter"));
}

You can now use it in your src/main.zig file:

const fastfilter = @import("fastfilter");

Ran into trouble?

Triple-check you followed the build.zig.zon instructions correctly, it’s easy to mess that part up.
