Enum interpreter::TraversalBreak

source · 
pub enum TraversalBreak {
    ReturnValue(Rc<Value>),
    Error(Error),
}
Expand description

Represents a break in traversal of the AST.

The reasons we would want to stop traversal are:

  1. We encountered an error.
  2. The AST contains a return statement, and we need to stop traversal of the current branch and return the value back to the start of that branch.
