Confused function aliases

[harisraharjo]

So I'm trying to create a dynamic matrix with nalgebra like let dm3 = DMatrix::from_fn(3, 3, |r, c| if r == c { 1.0 } else { 0.0 }). This code is a copy from this official file.

Current Behaviour

Rust-analyzer is giving me this error eventhough the cargo check command says it works just fine

Expected Behaviour

Rust-analyzer should be able to know different types of function aliases and not show error

rust-analyzer version: 5d5bbec 2022-05-09 stable
rustc version: 1.60.0 (7737e0b5c 2022-04-04)
relevant settings: vscode { Check On Save: Command = clippy }

Probably a dupe of #544.

#5441, that is ;)

Just to add information:
rust-analyzer can detect it perfectly if it's inside a trait. E.g as default implementation
