Variants

ZeroChars
Expand description

Expected 1 char, but 0 were found.

MoreThanOneChar
Expand description

Expected 1 char, but more than 1 were found.

LoneSlash
Expand description

Escaped ’' character without continuation.

InvalidEscape
Expand description

Invalid escape character (e.g. ‘\z’).

BareCarriageReturn
Expand description

Raw ‘\r’ encountered.

BareCarriageReturnInRawString
Expand description

EscapeOnlyChar
Expand description

Unescaped character that was expected to be escaped (e.g. raw ‘\t’).

TooShortHexEscape
Expand description

Numeric character escape is too short (e.g. ‘\x1’).

InvalidCharInHexEscape
Expand description

Invalid character in numeric escape (e.g. ‘\xz’)

OutOfRangeHexEscape
