Struct Visitor

source
struct Visitor<'a> {
    locals: &'a mut Vector<VarId, Var>,
    statements: Vec<Statement>,
    place_mutability_stack: Vec<bool>,
    span: Span,
}
Expand description

Visitor to transform the operands by introducing intermediate let statements.

We explore the statements without diving into substatements, and in particular explore the places and operands. Places always appear as destinations we are writing to. While we explore the places/operands present in a statement, We temporarily store the new statements inside the visitor. Once we’ve finished exploring the statement, we insert those before the statement.
