Implementations

impl ParseError

pub fn new(kind: ParseErrorKind, position: usize, message: String) -> Self

Create a new parse error

pub fn unterminated_string(position: (usize, usize)) -> Self

Create an error for unterminated string literals

pub fn invalid_token(token: String, position: (usize, usize)) -> Self

Create an error for invalid tokens

pub fn unicode_error(_message: &str) -> Self

Create an error for Unicode-related issues

pub fn scanner_error_simple(message: &str) -> Self

Create a simple scanner error

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParseError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<Error> for ParseError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for ParseError

fn from(err: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<ScannerError> for ParseError

fn from(err: ScannerError) -> Self

Converts to this type from the input type.

impl From<UnicodeError> for ParseError

fn from(err: UnicodeError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for ParseError

fn from(err: Utf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> 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.

impl Serialize for ParseError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ParseError

impl StructuralPartialEq for ParseError
