Struct SimpleParseError

pub struct SimpleParseError<P>
where
    P: UserPosn,
{
    pub ch: char,
    pub pos: P,
}

A simple implementation of a type supporting LexerError

An error in parsing a token

P : UserPosn

Fields

ch: char

The character which could not be matched to a token

pos: P

The position of the character in the stream

Trait Implementations

impl<P> Clone for SimpleParseError<P>

where P: UserPosn + Clone,

fn clone(&self) -> SimpleParseError<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P> Debug for SimpleParseError<P>

where P: UserPosn + Debug,

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

Formats the value using the given formatter.

impl<P> Display for SimpleParseError<P>

where P: UserPosn,

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

Formats the value using the given formatter.

impl<P> Error for SimpleParseError<P>

where P: UserPosn,

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<P> LexerError<P> for SimpleParseError<P>

where P: UserPosn,

fn failed_to_parse(pos: P, ch: char) -> Self

Return an error indicating that a bad character (could not be matched for a token) has occurred at the position indicated by the state

impl<P> PartialEq for SimpleParseError<P>

where P: UserPosn + PartialEq,

fn eq(&self, other: &SimpleParseError<P>) -> 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<P> Eq for SimpleParseError<P>

where P: UserPosn + Eq,

impl<P> StructuralPartialEq for SimpleParseError<P>

where P: UserPosn,
