Struct rustc_hir::hir::WhereClause

pub struct WhereClause<'hir> {
    pub predicates: &'hir [WherePredicate<'hir>],
    pub span: Span,
}

A where-clause in a definition.

Fields

predicates: &'hir [WherePredicate<'hir>]

span: Span

Implementations

impl WhereClause<'_>

pub fn span(&self) -> Option<Span>

pub fn span_for_predicates_or_empty_place(&self) -> Span

The WhereClause under normal circumstances points at either the predicates or the empty space where the where clause should be. Only of use for diagnostic suggestions.

pub fn tail_span_for_suggestion(&self) -> Span

Span where further predicates would be suggested, accounting for trailing commas, like in fn foo<T>(t: T) where T: Foo, so we don’t suggest two trailing commas.

Trait Implementations

impl<'hir> Debug for WhereClause<'hir>

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

Formats the value using the given formatter.

impl<'hir, __CTX> HashStable<__CTX> for WhereClause<'hir> where
    __CTX: HashStableContext, 

fn hash_stable(&self, __hcx: &mut __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.
