Enum rustc_hir_typeck::pat::AdjustMode
source · enum AdjustMode {
Peel,
Reset,
ResetAndConsumeRef(Mutability),
Pass,
}
Expand description
Mode for adjusting the expected type and binding mode.
Variants§
Peel
Peel off all immediate reference types.
Reset
Reset binding mode to the initial mode. Used for destructuring assignment, where we don’t want any match ergonomics.
ResetAndConsumeRef(Mutability)
Produced by ref patterns. Reset the binding mode to the initial mode, and if the old biding mode was by-reference with mutability matching the pattern, mark the pattern as having consumed this reference.
Pass
Pass on the input binding mode and expected type.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
