Module types 

ComposableError and error context structures Error types and utilities.

This module provides a set of types and utilities for handling errors in a structured and composable way.

Examples

use error_rail::{ComposableError, ErrorContext};

let err = ComposableError::new("database connection failed")
    .with_context(ErrorContext::tag("db"))
    .set_code(500);

assert!(err.to_string().contains("database connection failed"));
assert_eq!(err.error_code(), Some(500));
