Struct rustc_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.
