2020-06-26Explain move errors that occur due to method calls involving `self`Aaron Hill-1/+6
This is a re-attempt of #72389 (which was reverted in #73594) Instead of using `ExpnKind::Desugaring` to represent operators, this PR checks the lang item directly.
2020-06-24Provide suggestions for some moved value errorsEsteban Küber-0/+228
When encountering an used moved value where the previous move happened in a `match` or `if let` pattern, suggest using `ref`. Fix #63988. When encountering a `&mut` value that is used in multiple iterations of a loop, suggest reborrowing it with `&mut *`. Fix #62112.

2020-06-15Rollup merge of #72598 - Aaron1011:feature/fnmut-capture-span, r=nikomatsakisRalf Jung-0/+3
Display information about captured variable in `FnMut` error Fixes #69446 When we encounter a region error involving an `FnMut` closure, we display a specialized error message. However, we currently do not tell the user which upvar was captured. This makes it difficult to determine the cause of the error, especially when the closure is large. This commit records marks constraints involving closure upvars with `ConstraintCategory::ClosureUpvar`. When we decide to 'blame' a `ConstraintCategory::Return`, we additionall store the captured upvar if we found a `ConstraintCategory::ClosureUpvar` in the path. When generating an error message, we point to relevant spans if we have closure upvar information available. We further customize the message if an `async` closure is being returned, to make it clear that the captured variable is being returned indirectly.

2020-02-03Auto merge of #67668 - matthewjasper:or-patterns, r=pnkfelixbors-0/+205
Implement MIR lowering for or-patterns This is the last thing needed to get meaningful run-pass tests for or-patterns. There probably need to be more tests before stabilizing this, but the most important cases should have been covered. Note: we can generate exponentially large MIR CFGs when using or-patterns containing bindings, type ascriptions, or that are for a match arm with a guard. `src/test/mir-opt/exponential-or.rs` shows the best case for what we currently do. cc #54883 closes #60350 closes #67514 cc @Centril r? @pnkfelix

Address inconsistency in using "is" with "declared here" "is" was generally used for NLL diagnostics, but not other diagnostics. Using "is" makes the diagnostics sound more natural and readable, so it seems sensible to commit to them throughout. r? @Centril
