Struct rustc_ast::ast::WhereClause

source · [−]

pub struct WhereClause {
    pub has_where_token: bool,
    pub predicates: Vec<WherePredicate>,
    pub span: Span,
}

Expand description

A where-clause in a definition.

Fields

has_where_token: bool

true if we ate a where token: this can happen if we parsed no predicates (e.g. struct Foo where {}). This allows us to accurately pretty-print in nt_to_tokenstream

predicates: Vec<WherePredicate>span: Span
