Trait FromExternalError

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

Available on crate feature mtls only.

This trait is required by the map_res combinator to integrate error types from external functions, like std::str::FromStr

Required Methods

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

Creates a new error from an input position, an ErrorKind indicating the wrapping parser, and 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.
