Trait kparse::KParseError

pub trait KParseError<C, I> {
    type WrappedError: Debug;

    // Required methods
    fn from(code: C, span: I) -> Self;
    fn code(&self) -> Option<C>;
    fn span(&self) -> Option<I>;

    fn with_code(self, code: C) -> Self;
}

This trait catches the essentials for an error type within this library.

It is implemented for E, nom::Err<E> and Result<(I,O), nom::Err<E>>.

Required Associated Types

type WrappedError: Debug

The base error type.

Required Methods

fn from(code: C, span: I) -> Self

Create a matching error.

fn code(&self) -> Option<C>

Returns the error code if self is Result::Err and it’s not nom::Err::Incomplete.

fn span(&self) -> Option<I>

Returns the error span if self is Result::Err and it’s not nom::Err::Incomplete.

fn err(&self) -> Option<&Self::WrappedError>

Returns the error if self is Result::Err and it’s not nom::Err::Incomplete.

fn parts(&self) -> Option<(C, I, &Self::WrappedError)>

Returns all the parts if self is Result::Err and it’s not nom::Err::Incomplete.

fn with_code(self, code: C) -> Self

Changes the error code.
