Macro impl_error_context 

macro_rules! impl_error_context {
    ($type:ty) => { ... };
}

Implements IntoErrorContext for a custom type.

This macro simplifies the implementation of the IntoErrorContext trait for user-defined types. It converts the type into an ErrorContext using its Display implementation.

Arguments

• $type - The type to implement IntoErrorContext for.

Examples

use error_rail::{impl_error_context, ErrorContext, traits::IntoErrorContext};
use std::fmt;

struct MyError {
    code: u32,
}

impl fmt::Display for MyError {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "Error code: {}", self.code)
    }
}

impl_error_context!(MyError);

let err = MyError { code: 404 };
let ctx = err.into_error_context();
assert_eq!(ctx.to_string(), "Error code: 404");
