ziglibs/s2s

A zig binary serialization format.

s2s's Issues

Add serialization/deserialization hook support for structs/unions

Similarly to how std.fmt supports adding a format() function to a struct or union, s2s should support it for custom serialization/deserialization or for when a type isn't fully supported. This would help with unsupported types that can't easily be serialized due to recursiveness.

Update to new build API

See ziglang/zig#18160

error on test

when i run test give me this error

Bug serializing and deserializing slices

    var known_at_runtime_zero: usize = 0;
    const hello = [_][]const u8{"hello"};
    //@compileLog(hello);
    // Compile Log Output:
    //@as([1][]const u8, .{ .{ 104, 101, 108, 108, 111 } })
    try testSerDesAlloc([1][]const u8, hello);

gives error trace

But it can clearly be seen that the expected and found bytes are the same

And on a related issue these test cases also fails

    try testSerDesPtrContentEquality(*const [1][]const u8, hello[0..]);
    try testSerDesSliceContentEquality([]const []const u8, hello[known_at_runtime_zero..]);

A futher example

    const K = struct { value: u8 };
    const works = [_]K{.{ .value = 7 }};
    try testSerDesAlloc([1]K, works); //passes test which as expected

    //doesn't pass test ,I think the errors are related to the above
    var doesnt_works = works;
    try testSerDesAlloc(*[1]K, doesnt_works[0..]);
    try testSerDesAlloc([]K, doesnt_works[known_at_runtime_zero..]);

This is a reproducer of an error I am getting while using s2s in my project. I'm I misunderstanding how to use s2s or this is a genuine bug with slice ?
