Struct Error

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

Available on crate feature mtls only.

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 for Error<I>

where I: Debug,

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

Formats the value using the given formatter.

impl<I> Display for Error<I>

where I: Display,

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

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

Formats the value using the given formatter.

impl<I> Error for Error<I>

where I: Debug + Display,

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<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) -> Error<I>

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) -> Error<I>

Creates an error from the input position and an ErrorKind

fn append(_: I, _: ErrorKind, other: Error<I>) -> Error<I>

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 for Error<I>

where I: PartialEq,

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.
