Auto merge of #148302 - folkertdev:non-rustic-unsized, r=bjorn3

error on non-rustic ABIs using unsized parameters

tracking issue: https://github.com/rust-lang/rust/issues/48055

This came up in https://github.com/rust-lang/rust/pull/144529#discussion_r2470214068.

The idea is that the layout of an unsized type is unstable (following the rust layout rules), and hence stable ABIs should not use unsized types. On stable, unsized types (or generics with a `?Sized` bound) are not accepted as parameters, so the errors introduced by this PR can only be observed when the unstable `unsized_fn_params` feature is enabled.

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
