Matthias Krüger db77788dc5 Rollup merge of #132939 - uellenberg:suggest-deref, r=oli-obk ... Suggest using deref in patterns Fixes #132784 This changes the following code: ```rs use std::sync::Arc; fn main() { let mut x = Arc::new(Some(1)); match x { Some(_) => {} None => {} } } ``` to output ```rs error[E0308]: mismatched types --> src/main.rs:5:9 | LL | match x { | - this expression has type `Arc<Option<{integer}>>` ... LL | Some(_) => {} | ^^^^^^^ expected `Arc<Option<{integer}>>`, found `Option<_>` | = note: expected struct `Arc<Option<{integer}>>` found enum `Option<_>` help: consider dereferencing to access the inner value using the Deref trait | LL | match *x { | ~~ ``` instead of ```rs error[E0308]: mismatched types --> src/main.rs:5:9 | 4 | match x { | - this expression has type `Arc<Option<{integer}>>` 5 | Some(_) => {} | ^^^^^^^ expected `Arc<Option<{integer}>>`, found `Option<_>` | = note: expected struct `Arc<Option<{integer}>>` found enum `Option<_>` ``` This makes it more obvious that a Deref is available, and gives a suggestion on how to use it in order to fix the issue at hand.		2024-12-14 23:56:28 +01:00
