Enum lrpar::parser::ParseRepair

pub enum ParseRepair<StorageT: Hash> {
    Insert(TIdx<StorageT>),
    Delete(Lexeme<StorageT>),
    Shift(Lexeme<StorageT>),
}

After a parse error is encountered, the parser attempts to find a way of recovering. Each entry in the sequence of repairs is represented by a ParseRepair.

Variants

Insert(TIdx<StorageT>)

Insert a Symbol::Token.

Delete(Lexeme<StorageT>)

Delete a symbol.

Shift(Lexeme<StorageT>)

Shift a symbol.
