Trait Implementations

impl Clone for ParserErrors[+]

[+] Show hidden undocumented items

fn clone(&self) -> ParserErrors[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl<I> ContextError<I> for ParserErrors[+]

[+] Show hidden undocumented items

fn add_context(_input: I, ctx: &'static str, other: Self) -> Self[−]

create a new error from an input position, a static string and an existing error. This is used mainly in the [context] combinator, to add user friendly information to errors when backtracking through a parse tree

impl Debug for ParserErrors[+]

[+] Show hidden undocumented items

fn fmt(&self, f: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl Display for ParserErrors[+]

[+] Show hidden undocumented items

fn fmt(&self, f: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl Error for ParserErrors[+]

[+] Show hidden undocumented items

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<I> ParseError<I> for ParserErrors[+]

[+] Show hidden undocumented items

fn from_error_kind(_input: I, kind: ErrorKind) -> Self[−]

creates an error from the input position and an [ErrorKind]

fn append(_input: I, kind: ErrorKind, other: Self) -> Self[−]

combines an existing error with a new one created from the input position and an [ErrorKind]. This is useful when backtracking through a parse tree, accumulating error context on the way

fn from_char(_input: I, c: char) -> Self[−]

creates an error from an input position and an expected character

fn or(self, other: Self) -> Self[−]

combines two existing error. This function is used to compare errors generated in various branches of [alt]

impl PartialEq<ParserErrors> for ParserErrors[+]

[+] Show hidden undocumented items

fn eq(&self, other: &ParserErrors) -> bool[−]

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

fn ne(&self, other: &ParserErrors) -> bool[−]

This method tests for !=.
