Implementation Details
When an error is encountered when iterating through
Parser<I>
, a while loop is used to continue iterating through the tokens until an entry that isn't an error is found. This is explained in the comments as part of the initial commit:A unit test has been added to test and demonstrate this functionality.
Note: No functionality to format parse errors has been implemented in this PR; however, this will be done if needed (perhaps in this PR?).
