Trait JoinToTokensError

pub trait JoinToTokensError {
    // Required method
    fn join(self, error: impl ToTokensError + 'static) -> Error;
}

Allows to call .join(..) on any impl ToTokensError

Required Methods

fn join(self, error: impl ToTokensError + 'static) -> Error

Joins two Errors

use manyhow::error_message;

error_message!("test").join(error_message!("another"));

Some errors like [manyhow::Error] and [manyhow::ErrorMessage] can also be “added”:

use manyhow::{error_message, Error};
error_message!("Hello Rust!") + error_message!("Hello 🦀!")
Error::from(error_message!("Hello Rust!")) + error_message!("Hello 🦀!")

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.
