2022-11-23Add regression test for issue 99938est31-0/+31
That issue was a dupe of 99852, but it's always better to have multiple regression tests rather than one.
2022-11-14Show a note where a macro failed to matchNilstrieb-0/+6
This shows a small note on what the macro matcher was currently processing to aid with "no rules expected the token X" errors.
2022-10-14Suppress irrefutable let patterns lint for prefixes in match guardsest31-14/+23
In match guards, irrefutable prefixes might use the bindings created by the match pattern. Ideally, we check for this, but we can do the next best thing and just not lint for irrefutable prefixes in match guards.
2022-10-06Rollup merge of #102708 - TaKO8Ki:improve-eqeq-suggestion, r=estebankMatthias Krüger-2/+2
Suggest `==` to wrong assign expr Given the following code: ```rust fn main() { let x = 3; let y = 3; if x == x && y = y { println!("{}", x); } } ``` Current output is: ``` error[E0308]: mismatched types --> src/main.rs:4:18 | 4 | if x == x && y = y { | ^ expected `bool`, found integer error[E0308]: mismatched types --> src/main.rs:4:8 | 4 | if x == x && y = y { | ^^^^^^^^^^^^^^^ expected `bool`, found `()` ``` This adds a suggestion: ```diff error[E0308]: mismatched types --> src/main.rs:6:18 | 6 | if x == x && y = y { | ^ expected `bool`, found integer error[E0308]: mismatched types --> src/main.rs:6:8 | 6 | if x == x && y = y { | ^^^^^^^^^^^^^^^ expected `bool`, found `()` | + help: you might have meant to compare for equality + | + 6 | if x == x && y == y { + | + ``` And this fixes a part of #97469

2022-07-07On partial uninit error point at where we need initEsteban Küber-9/+21
When a binding is declared without a value, borrowck verifies that all codepaths have *one* assignment to them to initialize them fully. If there are any cases where a condition can be met that leaves the binding uninitialized or we attempt to initialize a field of an unitialized binding, we emit E0381. We now look at all the statements that initialize the binding, and use them to explore branching code paths that *don't* and point at them. If we find *no* potential places where an assignment to the binding might be missing, we display the spans of all the existing initializers to provide some context.

2022-03-16Extend the irrefutable_let_patterns lint to let chainsest31-10/+158
Only look for complete suffixes or prefixes of irrefutable let patterns, so that an irrefutable let pattern in a chain surrounded by refutable ones is not linted, as it is an useful pattern.

2021-03-10Rollup merge of #82217 - m-ou-se:edition-prelude, r=nikomatsakisDylan DPC-1/+1
Edition-specific preludes This changes `{std,core}::prelude` to export edition-specific preludes under `rust_2015`, `rust_2018` and `rust_2021`. (As suggested in https://github.com/rust-lang/rust/issues/51418#issuecomment-395630382.) For now they all just re-export `v1::*`, but this allows us to add things to the 2021edition prelude soon. This also changes the compiler to make the automatically injected prelude import dependent on the selected edition. cc `@rust-lang/libs` `@djc`
