//! # Qubit IO
//!
//! Runtime-neutral synchronous and asynchronous item-stream I/O for Rust.
//!
//! [`Input`] and [`Output`] model synchronous item transfer. [`AsyncInput`] and
//! [`AsyncOutput`] expose the same boundary through `Pin` and `Poll` without
//! selecting an executor. Standard-library byte streams implement the
//! synchronous traits automatically; optional newtypes bridge Tokio and
//! `futures-io` asynchronous streams without overlapping blanket impls.
//! [`AsyncClose`] represents a real close operation rather than a flush.
//! Named futures preserve multi-poll progress, while [`PinnedAsyncInputExt`]
//! and [`PinnedAsyncOutputExt`] support pinned `!Unpin` values and trait
//! objects. Async implementations must register the current waker before
//! returning `Pending`, transfer no items on `Pending` or errors, and prevent
//! `WouldBlock` and `Interrupted` from crossing the trait boundary.
//!
//! Item-oriented buffering includes [`BufferedInput`], [`BufferedOutput`],
//! [`AsyncBufferedInput`], and [`AsyncBufferedOutput`]. Limit, counting, and
//! checksum wrappers are available for both operation modes. Binary and text
//! codecs remain in sibling crates.
//!
//! The concrete trait definitions and wrapper types live in dedicated modules
//! and are re-exported from the crate root for ergonomic use.
// qubit-style: allow coverage-cfg
