Enum webidl_parser::LexicalErrorCode
[−]
[src]
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.
