error: functions in `extern` blocks cannot have `const` qualifier
Fix diagnostic for qualifier in extern block Closes: https://github.com/rust-lang/rust/issues/123306
2024-04-03 00:43:54 +00:00
--> $DIR/no-const-fn-in-extern-block.rs:2:5
Add support for 'extern const fn' This works just as you might expect - an 'extern const fn' is a 'const fn' that is callable from foreign code. Currently, panicking is not allowed in consts. When RFC 2345 is stabilized, then panicking in an 'extern const fn' will produce a compile-time error when invoked at compile time, and an abort when invoked at runtime. Since this is extending the language (we're allowing the `const` keyword in a new context), I believe that this will need an FCP. However, it's a very minor change, so I didn't think that filing an RFC was necessary. This will allow libc (and other FFI crates) to make many functions `const`, without having to give up on making them `extern` as well.
