What it does

Detects an exhaustive pattern match and suggests replacing it with _

e.g.
`fn main() {
let b = A::B;

match b { A::B | A::C => println!("Pattern is verbose") } 

}

#[derive(PartialEq)]
enum A {
B, C
}`

In the above case it's a little simple but when doing things with nested tuples something might be missed

Advantage

• _ is easier to read, epecially in cases of mathicng with nested tuples

Drawbacks

Example

<code> fn main() { let b = A::B; let a = 11; match (a, b) { (10, A::B | A::C) => println!("Pattern is verbose"), _ => println!("Pattern is verbose") } } #[derive(PartialEq)] enum A { B, C }

Could be written as:

<code> fn main() { let b = A::B; let a = 11; match (a, b) { (10, _) => println!("Pattern is verbose"), _ => println!("Pattern is verbose") } } #[derive(PartialEq)] enum A { B, C }
