pub struct Param<'tcx> {
    pub pat: Option<Box<Pat<'tcx>>>,

Description of a type-checked function parameter.

Fields

pat: Option<Box<Pat<'tcx>>>

The pattern that appears in the parameter list, or None for implicit parameters.

ty: Ty<'tcx>

The possibly inferred type.

ty_span: Option<Span>

Span of the explicitly provided type, or None if inferred for closures.

self_kind: Option<ImplicitSelfKind>

Whether this param is self, and how it is bound.

hir_id: Option<HirId>

HirId for lints.

Trait Implementations

impl<'tcx> Clone for Param<'tcx>

fn clone(&self) -> Param<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for Param<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for Param<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

Layout

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.
