Struct AssignmentRenamer

pub struct AssignmentRenamer<'a> {
    pub assigner: &'a Assigner,
    pub rename_table: RenameTable,
    pub is_lhs: bool,
}

An AssignmentRenamer renames the left-hand side of all assignment statements in an AST node. The new names are propagated to all following identifiers.

Fields

assigner: &'a Assigner

rename_table: RenameTable

is_lhs: bool

Implementations

impl<'a> AssignmentRenamer<'a>

pub fn new(assigner: &'a Assigner) -> Self

Initialize a new AssignmentRenamer.

pub fn load(&mut self, entries: impl Iterator<Item = (Symbol, Symbol, NodeID)>)

Load the internal rename table with a set of entries.

pub fn clear(&mut self)

Clear the internal rename table.
