👎Deprecated since 1.0.0:

register_error_hook silently drops registration failures; use try_register_error_hook instead

Register a callback to be called when errors are created.

Deprecated since 1.0.0. This variant silently discards the registration failure when a hook is already installed. Use try_register_error_hook instead — it returns the failure explicitly so callers can decide how to handle the double-registration case.

Example

use error_forge::macros::{try_register_error_hook, ErrorLevel};

let _ = try_register_error_hook(|ctx| {
    match ctx.level {
        ErrorLevel::Debug => println!("DEBUG: {} ({})", ctx.caption, ctx.kind),
        ErrorLevel::Info => println!("INFO: {} ({})", ctx.caption, ctx.kind),
        ErrorLevel::Warning => println!("WARNING: {} ({})", ctx.caption, ctx.kind),
        ErrorLevel::Error => println!("ERROR: {} ({})", ctx.caption, ctx.kind),
        ErrorLevel::Critical => println!("CRITICAL: {} ({})", ctx.caption, ctx.kind),
        // `ErrorLevel` is `#[non_exhaustive]` — minor releases
        // may add new severity levels.
        _ => println!("OTHER: {} ({})", ctx.caption, ctx.kind),
    }
});
