Struct libslide::parser::errors::MismatchedClosingDelimiter

pub(crate) struct MismatchedClosingDelimiter;

All opening delimiters with closing pairs must have that closing delimiter as a correctly-ordered complement in a slide program. In particular,

• ( and ) are complements (parantheses)
• [ and ] are complements (brackets)

The most obvious case for a mismatch is when an incorrect complement is used, for example in (1+2] or [1+2).

A complement to this is that nesting order must be obeyed. That is, ([1 + 2]) is valid but ([1 + 2)] is not.

Finally, a more subtle case may be when one set of delimiters is not properly closed, as in the case

([1 + 2)
       ^- expected closing `]`
