Expand description
Errors and warnings that can occur during string unescaping.
Variants§
ZeroChars
Expected 1 char, but 0 were found.
MoreThanOneChar
Expected 1 char, but more than 1 were found.
LoneSlash
Escaped ’' character without continuation.
InvalidEscape
Invalid escape character (e.g. ‘\z’).
BareCarriageReturn
Raw ‘\r’ encountered.
BareCarriageReturnInRawString
Raw ‘\r’ encountered in raw string.
EscapeOnlyChar
Unescaped character that was expected to be escaped (e.g. raw ‘\t’).
TooShortHexEscape
Numeric character escape is too short (e.g. ‘\x1’).
InvalidCharInHexEscape
Invalid character in numeric escape (e.g. ‘\xz’)
OutOfRangeHexEscape
Character code in numeric escape is non-ascii (e.g. ‘\xFF’).
NoBraceInUnicodeEscape
‘\u’ not followed by ‘{’.
InvalidCharInUnicodeEscape
Non-hexadecimal value in ‘\u{..}’.
EmptyUnicodeEscape
‘\u{}’
UnclosedUnicodeEscape
No closing brace in ‘\u{..}’, e.g. ‘\u{12’.
LeadingUnderscoreUnicodeEscape
‘\u{_12}’
OverlongUnicodeEscape
More than 6 characters in ‘\u{..}’, e.g. ‘\u{10FFFF_FF}’
LoneSurrogateUnicodeEscape
Invalid in-bound unicode character code, e.g. ‘\u{DFFF}’.
OutOfRangeUnicodeEscape
Out of bounds unicode character code, e.g. ‘\u{FFFFFF}’.
UnicodeEscapeInByte
Unicode escape code in byte literal.
NonAsciiCharInByte
Non-ascii character in byte literal, byte string literal, or raw byte string literal.
UnskippedWhitespaceWarning
After a line ending with ’', the next line contains whitespace characters that are not skipped.
MultipleSkippedLinesWarning
After a line ending with ’', multiple lines are skipped.
