variadic functions: remove list of supported ABIs from error I think this list is problematic for multiple reasons: - It is bound to go out-of-date as it is in a very different place from where we actually define which functions support varagrs (`fn supports_varargs`). - Many of the ABIs we list only work on some targets; it makes no sense to mention "aapcs" as a possible ABI when building for x86_64. (This led to a lot of confusion in https://github.com/rust-lang/rust/issues/110505 where the author thought they should use "cdecl" and then were promptly told that "cdecl" is not a legal ABI on their target.) - Typically, when the programmer wrote `extern "foobar"`, it is because they need the "foobar" ABI. It is of little use to tell them that there are other ABIs with which varargs would work. Cc ``@workingjubilee`` |

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).
