Multiple of such tools exist and have done for years. Serde isn’t a Rust-core project, and similarly the Gleam alternatives are not Gleam-core.

Rust has macros that make serde very convenient, which Gleam doesn't have.

Could you point to a solution that provides serde level of convenience?

Edit: The difference with generating code (like with Gleam) and having macros generate the code from a few tags is quite big. Small tweaks are immediately obvious in serde in Rust, but they drown in the noise in the complete serialization code like with the Gleam tools.

To be fair, Rust's proc macros are only locally optimal:

While they're great to use, they're only okay to program.

Your proc-macro needs to live in another crate, and writing proc macros is difficult.

Compare this to dependently typed languages og Zig's comptime: It should be easier to make derive(Serialize, Deserialize) as compile-time features inside the host language.

When Gleam doesn't have Rust's derivation, it leaves for a future where this is solved even better.

In Gleam code generators are most commonly used, similar to in C#, Go, or Elm.

		Yes, my point is that it's not a good experience.
