//! Rust-Bitcoin IO Library
|
||
|
|
//!
|
||
|
|
//! Because the core `std::io` module is not yet exposed in `no-std` Rust, building `no-std`
|
||
|
|
//! applications which require reading and writing objects via standard traits is not generally
|
||
|
|
//! possible. While there is ongoing work to improve this situation, this module is not likely to
|
||
|
|
//! be available for applications with broad rustc version support for some time.
|
||
|
|
//!
|
||
|
|
//! Thus, this library exists to export a minmal version of `std::io`'s traits which `no-std`
|
||
|
|
//! applications may need. With the `std` feature, these traits are also implemented for the
|
||
|
|
//! `std::io` traits, allowing standard objects to be used wherever the traits from this crate are
|
||
|
|
//! required.
|
||
|
|
//!
|
||
|
|
//! This traits are not one-for-one drop-ins, but are as close as possible while still implementing
|
||
|
|
//! `std::io`'s traits without unnecessary complexity.
|
||
|
|
|
||
|
|
// Experimental features we need.
