Jayさん

Jaysan is a fast json library written in Zig. Currently supports serialization only.

var gpa = std.heap.GeneralPurposeAllocator(.{}){};

const Foo = struct {
    foo: i32,
    bar: []const u8,
};

const string = try json.stringifyAlloc(
    gpa.allocator(),
    Foo{
        .foo = 123,
        .bar = "Hello, world!",
    },
);

// {"foo":123,"bar":"Hello, world!"}
