Struct Error

pub struct Error<I> {
    pub input: I,
    pub code: ErrorKind,
}

default error type, only contains the error’ location and code

Fields

input: I

position of the error in the input data

code: ErrorKind

nom error code

Implementations

impl<I> Error<I>

pub fn new(input: I, code: ErrorKind) -> Error<I>

creates a new basic error

Trait Implementations

impl<I> ContextError<I> for Error<I>

fn add_context(_input: I, _ctx: &'static str, other: Self) -> Self

Creates 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<I: Debug> Debug for Error<I>

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

Formats the value using the given formatter.

impl<I: Display> Display for Error<I>

The Display implementation allows the std::error::Error implementation

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

Formats the value using the given formatter.

impl<I> ErrorConvert<Error<(I, usize)>> for Error<I>

fn convert(self) -> Error<(I, usize)>

Transform to another error type

impl<I> ErrorConvert<Error<I>> for Error<(I, usize)>

fn convert(self) -> Error<I>

Transform to another error type

impl<I, E> FromExternalError<I, E> for Error<I>

fn from_external_error(input: I, kind: ErrorKind, _e: E) -> Self

Create a new error from an input position and an external error

impl<I> ParseError<I> for Error<I>

fn from_error_kind(input: I, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(_: I, _: 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, _: char) -> Self

Creates an error from an input position and an expected character

fn or(self, other: Self) -> Self

Combines two existing errors. This function is used to compare errors generated in various branches of alt.

impl<I: PartialEq> PartialEq for Error<I>

fn eq(&self, other: &Error<I>) -> 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.
