Struct WrappedRoot 

pub struct WrappedRoot {
    pub start_of_input: Symbol,
    pub inner_root: Symbol,
    pub end_of_input: Symbol,
    pub root: Symbol,
}

We have a method for adding “wrapped” roots in the form: root ::= start_of_input ~ inner_root ~ end_of_input. See fn wrap_input.

Fields

start_of_input: Symbol

First symbol in the wrapping rule.

inner_root: Symbol

Second symbol in the wrapping rule.

end_of_input: Symbol

Third symbol in the wrapping rule.

root: Symbol

The LHS of the wrapping rule.
