Variants

InvalidEscape

Invalid escape character (e.g. ‘\z’).

BareCarriageReturn

Raw ‘\r’ encountered.

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}’.

Trait Implementations

impl Clone for EscapeError

fn clone(&self) -> EscapeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EscapeError

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

Formats the value using the given formatter.

impl Display for EscapeError

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

Formats the value using the given formatter.

impl Error for EscapeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<EscapeError> for LexerError

fn from(source: EscapeError) -> Self

Converts to this type from the input type.

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.
