Module error 

Error and Result Helpers

Provides shared boxed error helpers and result aliases used by generic callbacks, integration glue, and source error storage.

This module intentionally contains only type-erased error helpers. Concrete domain errors remain in their owning crates.

Use these helpers when the exact error type is deliberately unimportant or cannot be expressed conveniently, for example callback return types, generic defaults, and stored source errors. Prefer concrete error enums or structs for public APIs where callers need structured recovery.

Examples

use qubit_error::error::{BoxError, BoxResult, IntoBoxError};

fn parse_port(text: &str) -> BoxResult<u16> {
    text.parse::<u16>()
        .map_err(|error| error.into_box_error())
}

let port = parse_port("8080").expect("valid port should parse");
assert_eq!(port, 8080);

let error: BoxError = parse_port("bad").expect_err("invalid port should fail");
assert!(error.to_string().contains("invalid digit"));
