Enum RecoveryKind

#[non_exhaustive]
pub enum RecoveryKind {
    CPCTPlus,
    None,
}

What recovery algorithm should be used when a syntax error is encountered?

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CPCTPlus

The CPCT+ algorithm from Diekmann/Tratt “Don’t Panic! Better, Fewer, Syntax Errors for LR Parsers”.

None

Don’t use error recovery: return as soon as the first syntax error is encountered.
