Generate UUID

See more ULID/UUID Examples

Generates a version 4 UUID, using either uppercase or lowercase hex. Zig

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

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const sb = try chilkat.StringBuilder.init();
    defer sb.deinit();

    // Generate a lowercase UUID.
    var lowercase: bool = true;
    sb.appendUuid(lowercase) catch {};
    std.debug.print("{s}\n", .{try sb.getAsString(alloc)});

    // example: edb1bb24-e9be-4ada-98bd-c2d893f29f55

    lowercase = false;
    sb.clear();
    sb.appendUuid(lowercase) catch {};
    std.debug.print("{s}\n", .{try sb.getAsString(alloc)});
