Trait rocket::mtls::x509::der_parser::asn1_rs::nom::error::ParseError

pub trait ParseError<I>: Sized {
    // Required methods
    fn from_error_kind(input: I, kind: ErrorKind) -> Self;
    fn append(input: I, kind: ErrorKind, other: Self) -> Self;

    // Provided methods
    fn from_char(input: I, _: char) -> Self { ... }
    fn or(self, other: Self) -> Self { ... }
}

Available on crate feature mtls only.

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

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

Provided Methods

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.

Object Safety

This trait is not object safe.
