Struct syntax::ext::expand::PatIdentRenamer

pub struct PatIdentRenamer<'a> {
    // some fields omitted
}

Unstable (rustc_private)

A tree-folder that applies every rename in its list to the idents that are in PatKind::Ident patterns. This is more narrowly focused than IdentRenamer, and is needed for FnDecl, where we want to rename the args but not the fn name or the generics etc.
