Crate qubit_io 

Qubit IO

Small I/O trait utilities for Rust.

This crate provides named, object-safe composition traits for common std::io capability combinations and small extension traits for recurring standard-library I/O patterns. The concrete trait definitions live in dedicated modules and are re-exported from the crate root for ergonomic use.
