Trait FromExternalError

pub trait FromExternalError<I, E> {
    // Required method
    fn from_external_error(input: &I, kind: ErrorKind, e: E) -> Self;
}

Create a new error with an external error, from std::str::FromStr

This trait is required by the Parser::try_map combinator.

Required Methods

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

Like ParserError::from_error_kind but also include an external error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
