Struct pegtastic::error::ParseError

pub struct ParseError<L> {
    pub location: L,
    pub expected: ExpectedSet,
}

An error from a parse failure

Fields

location: L

The furthest position the parser reached in the input

expected: ExpectedSet

The set of literals that failed to match at that position

Trait Implementations

impl<L> Clone for ParseError<L> where
    L: Clone, 

fn clone(&self) -> ParseError<L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L> Debug for ParseError<L> where
    L: Debug, 

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

Formats the value using the given formatter.

impl<L> Display for ParseError<L> where
    L: Display, 

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

Formats the value using the given formatter.

impl<L> Eq for ParseError<L> where
    L: Eq, 

impl<L> Error for ParseError<L> where
    L: Debug + Display, 

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<L> PartialEq<ParseError<L>> for ParseError<L> where
    L: PartialEq<L>, 

fn eq(&self, other: &ParseError<L>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ParseError<L>) -> bool

This method tests for !=.
