Implementation

pub fn parseAlloc(allocator: std.mem.Allocator, bytes: []const u8) ParseError![]u8 {
    var aw: std.io.Writer.Allocating = .init(allocator);
    defer aw.deinit();
    const result = parseWrite(&aw.writer, bytes) catch |err| switch (err) {
        error.WriteFailed => return error.OutOfMemory,
    };
    switch (result) {
        .success => return aw.toOwnedSlice(),
        .failure => return error.InvalidLiteral,
    }
