Struct Expr
pub struct Expr { /* private fields */ }Description
Source expression with its exact byte range.
Implementations§
§impl Expr
impl Expr
pub fn rewrite_name_paths(
&self,
rewrite: impl FnMut(&NamePath) -> Option<NamePath>,
) -> Expr
pub fn rewrite_name_paths( &self, rewrite: impl FnMut(&NamePath) -> Option<NamePath>, ) -> Expr
Rewrite structurally named references without reparsing source text.
The callback visits bare ExprKind::Name and qualified
ExprKind::Path occurrences as one NamePath abstraction. Returning
None retains the occurrence; returning a path replaces it. Expression
topology and every expression/source range are preserved. Call callees
are structural NamePath values and are visited before their ordered
arguments.
