Enum webidl_parser::LexicalErrorCode

pub enum LexicalErrorCode {
    ExpectedCommentBlockEnd,
    ExpectedDecimalDigit,
    ExpectedEllipsis,
    ExpectedFloatExponent,
    ExpectedHexadecimalDigit,
    ExpectedKeywordInfinity,
    ExpectedStringLiteralEnd,
}

An enum of possible errors that can occur during lexing.

Variants

ExpectedCommentBlockEnd

Occurs when a block comment is not closed (e.g. /* this is a comment). Notably, this can only occur when the end of the file is reached as everything else will always be considered to be a part of the comment.

ExpectedDecimalDigit

Occurs in the specific case of lexing a float literal of the form -. with no following decimal digits.

ExpectedEllipsis

Occurs when .. is lexed with no following ..

ExpectedFloatExponent

Occurs when lexing a float literal that does not provide an exponent after the e (e.g. (582.13e).

ExpectedHexadecimalDigit

Occurs when lexing a hexadecimal literal that does not provide hexadecimal digits after the 0x.

ExpectedKeywordInfinity

Occurs when any leading substring of Infinity follows - but does not complete the keyword.

ExpectedStringLiteralEnd

Occurs when a string literal is not closed (e.g. "this is a string). Notably, this can only occur when the end of the file is reached as everything else will always be considered to be a part of the string.
