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 pretty-print accurately.

predicates: Vec<WherePredicate>span: Span

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.
