//! A library and application for flashing Espressif devices over Serial
//!
//! ## As an application
//!
//! [espflash] can be installed using `cargo install`, and additionally supports installation via [cargo-binstall]:
//!
//! ```bash
//! $ cargo install espflash
//! $ cargo binstall espflash
//! ```
//!
//! Flashing via a Raspberry Pi's internal UART is also possible, however this
//! functionality is gated behind the `raspberry` feature; if you would like to
//! enable this simply enable the feature when installing:
//!
//! ```bash
//! $ cargo install espflash --feature=raspberry
//! ```
//!
//! Note that this feature can only be enabled on a Raspberry Pi, as it depends
//! on the [rppal] package which will not build on most systems.
//!
//! ## As a library
//!
//! [espflash] can also be used as a library:
//!
//! ```toml
//! espflash = { version = "2.0", default-features = false }
//! ```
//!
//! We add `default-features` here to disable the `cli` feature, which is
//! enabled by default; you likely will not need any of these types or functions
//! in your application so there's no use pulling in the extra dependencies.
//!
//! Just like when using [espflash] as an application, you can enable the
//! `raspberry` feature to allow your dependent application to use the Raspberry
//! Pi's built-in UART:
//!
//! ```toml
//! espflash = { version = "2.0", default-features = false, features = ["raspberry"] }
//! ```
//!
//! [espflash]: https://crates.io/crates/espflash
//! [cargo-binstall]: https://github.com/cargo-bins/cargo-binstall
//! [rppal]: https://docs.rs/rppal/latest/rppal/
