### What it does
|
|
Check for the usage of `as _` conversion using inferred type.
|
|
|
|
### Why is this bad?
|
|
The conversion might include lossy conversion and dangerous cast that might go
|
|
undetected due to the type being inferred.
|
|
|
|
The lint is allowed by default as using `_` is less wordy than always specifying the type.
|
|
|
|
### Example
|
|
```
|
|
fn foo(n: usize) {}
|
|
let n: u16 = 256;
|
|
foo(n as _);
|
|
```
|
|
Use instead:
|
|
```
|
|
fn foo(n: usize) {}
|
|
let n: u16 = 256;
|
|
foo(n as usize);
|
|
``` |
