The adjustments are used later by ExprUseVisitor to build Place projections and without adjustments it can produce invalid result.
Includes documentation for: - general page structure - navigation - searching - themes - deep-linking Doesn't include docs on the settings page.
For example:
enum Ty {
Unit,
List(Box<Ty>),
}
fn foo(x: Ty) -> Ty {
match x {
Ty::Unit => Ty::Unit,
Ty::List(elem) => foo(elem),
}
}
Before, the only suggestion was to rewrap `elem` with `Ty::List`,
which is unhelpful and confusing:

= note: expected enum `Ty`
found struct `Box<Ty>`
Now, rustc will first suggest dereferencing the `Box`, which is most
likely what the user intended:

Apply adjustments for field expression even if inaccessible The adjustments are used later by ExprUseVisitor to build Place projections and without adjustments it can produce invalid result. Fixrust-lang#90483 `@rustbot` label: T-compiler
Suggest dereference of `Box` when inner type is expected
For example:
enum Ty {
Unit,
List(Box<Ty>),
}
fn foo(x: Ty) -> Ty {
match x {
Ty::Unit => Ty::Unit,
Ty::List(elem) => foo(elem),
}
}
Before, the only suggestion was to rewrap `inner` with `Ty::Wrapper`,
which is unhelpful and confusing:
