Expand description

A match pattern.

Patterns appear in match statements and some other contexts, such as let and if let.

Fields

id: NodeIdkind: PatKindspan: Spantokens: Option<LazyTokenStream>

Implementations

Attempt reparsing the pattern as a type. This is intended for use by diagnostics.

Walk top-down and call it in each place where a pattern occurs starting with the root pattern walk is called on. If it returns false then we will descend no further but siblings will be processed.

Is this a .. pattern?

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
