//! Iterators over text in morse code.
//!
//! ```rust
//! fn wait_for(duration: u8) {
//!     // ...
//! }
//! fn beep_for(duration: u8) {
//!     // ...
//! }
//!
//! for action in small_morse::encode("Hello in morse code!") {
//!     if action.state == small_morse::State::On {
//!         beep_for(action.duration);
//!     } else {
//!         wait_for(action.duration);
//!     }
//! }
//! ```
//!
//! This library is for encoding text into morse code (not the other way around yet).
//!
//! It works without the standard library.
