Errors 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.

NonAsciiCharInByteString

Non-ascii character in byte string literal.

Trait Implementations

impl Debug for EscapeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EscapeError

fn eq(&self, other: &EscapeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
