Struct VarReassigner

source 
pub struct VarReassigner<'a> {
    pub old_vars: &'a Arena<Variable>,
    pub new_vars: Arena<Variable>,
    pub vars: UnorderedHashMap<VariableId, VariableId>,
}
Expand description

Helper class to reassign variable ids according to the rebuild order.

Note that it can’t be integrated into the RebuildContext above because rebuild_remapping might call map_var_id on variables that are going to be removed.
