) -> Result<I::Domain, RecursionLimitError>
pub fn apply( &mut self, expr: &mut Plan<T> ) -> Result<I::Domain, RecursionLimitError>
An immutable fold (structural recursion) over a Plan instance.
Runs an abstract interpreter over the given expr
in a bottom-up
manner, keeping the ctx
field of the enclosing field up to date, and
returns the final result for the entire expr
.
At each step, the current expr
is passed along with the interpretation
result of itself and its children to an action
callback that can
optionally mutate it.
