Variants

InvalidToken

Generated by the parser when it encounters a token (or EOF) it did not expect.

Fields

location: usize

UnrecognizedEof

Generated by the parser when it encounters an EOF it did not expect.

Fields

location: usize

The end of the final token

expected: Vec<String>

The set of expected tokens: these names are taken from the grammar and hence may not necessarily be suitable for presenting to the user.

UnrecognizedToken

Generated by the parser when it encounters a token it did not expect.

Fields

token: (usize, Token, usize)

The unexpected token of type T with a span given by the two L values.

expected: Vec<String>

The set of expected tokens: these names are taken from the grammar and hence may not necessarily be suitable for presenting to the user.

ExtraToken

Generated by the parser when it encounters additional, unexpected tokens.

Fields

token: (usize, Token, usize)

User

Custom error type.

Fields

error: LexicalError
