pub struct WhereClause {
pub has_where_token: bool,
pub predicates: ThinVec<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 and provide correct suggestion diagnostics.
predicates: ThinVec<WherePredicate>
§span: Span
