    // Required method
    fn into_error_context(self) -> ErrorContext;
}

Expand description

Converts a type into an ErrorContext for error annotation.

This trait is used throughout the error handling pipeline to accept flexible context types when building composable errors.

§Implementing for Custom Types

If you need to use a custom type as error context, you have two options:

Use the impl_error_context! macro for types implementing Display:
ⓘ
```
impl_error_context!(MyCustomError);
```

Implement the trait manually:

use error_rail::{traits::IntoErrorContext, ErrorContext};

struct MyContext { user_id: u64 }

impl IntoErrorContext for MyContext {
    fn into_error_context(self) -> ErrorContext {
        ErrorContext::metadata("user_id", self.user_id.to_string())
    }
}
