The suggestion to remove generic parameters proposed by help did not remove comma

[A4-Tacks]

Code

type Result<T> = std::result::Result<T, ()>;

fn foo() -> Result<'static, ()> { Ok(()) }

fn main() { }

Current output

error[E0107]: type alias takes 0 lifetime arguments but 1 lifetime argument was supplied
 --> src/main.rs:3:13

3 | fn foo() -> Result<'static, ()> { Ok(()) }
  |             ^^^^^^ ------- help: remove this lifetime argument
  |             |

 --> src/main.rs:1:6
  |
1 | type Result<T> = std::result::Result<T, ()>;

Rationale and extra context

rust-lang/rust-analyzer#17727

Due to not removing the comma, rust-analyzer still has an error after quick fix

It looks like that may have been fixed by b30fdec, can you check what happens on the latest nightly? (Unfortunately the playground hasn't been updated to something recent enough yet).

rustc 1.82.0-nightly (7c2012d 2024-07-26)
The cargo check output doesn't seem to have changed

In the example of b30fdec, it seems that the test case does not include a comma that removes the first parameter, but rather the tail parameter

Cc @estebank since you did #127374, might be a quick fixup

This doesn't seem to remove the comma on the left either

type Result<T> = std::result::Result<T, ()>;

fn foo() -> Result<(), 'static> { Ok(()) }

fn main() { }

output:

error[E0107]: type alias takes 0 lifetime arguments but 1 lifetime argument was supplied
