Expand description
This trait must be implemented by the error type of a nom parser.
There are already implementations of it for (Input, ErrorKind)
and VerboseError<Input>
.
It provides methods to create an error from some combinators,
and combine existing errors in combinators like alt
.
Required Methods
fn from_error_kind(input: I, kind: ErrorKind) -> Self
fn from_error_kind(input: I, kind: ErrorKind) -> Self
Creates an error from the input position and an ErrorKind
Provided Methods
Creates an error from an input position and an expected character
