//! This crate provides an implementation of a general suffix automaton.
//!
//! ```mermaid
//! flowchart LR
//! init((ε))
//! a((a))
//! b((b))
//! ab((ab))
//! bc(((bc)))
//! abc((abc))
//! abcb((abcb))
//! abcbc(((abcbc)))
//!
//! init -- a --> a
//! init -- b --> b
//! a -- b --> ab
//! b -- c --> bc
//! init -- c --> bc
//! ab -- c --> abc
//! bc -- b --> abcb
//! abc -- b --> abcb
//! abcb -- c --> abcbc
//! ```
//!
//! > The suffix automaton of abcbc.
//!
//! # Examples
//!
//! ```rust
//! use general_sam::{GeneralSam, BTreeTransTable};
//!
//! let sam = GeneralSam::<BTreeTransTable<_>>::from_bytes("abcbc");
//!
//! // "cbc" is a suffix of "abcbc"
//! assert!(sam.get_root_state().feed_bytes("cbc").is_accepting());
//!
//! // "bcb" is not a suffix of "abcbc"
//! assert!(!sam.get_root_state().feed_bytes("bcb").is_accepting());
//! ```
//!
//! ```rust
//! use general_sam::{GeneralSam, BTreeTransTable};
//!
//! let sam = GeneralSam::<BTreeTransTable<_>>::from_chars("abcbc");
//!
//! let mut state = sam.get_root_state();
//!
//! // "b" is not a suffix but at least a substring of "abcbc"
//! state.feed_chars("b");
//! assert!(!state.is_accepting());
//!
//! // "bc" is a suffix of "abcbc"
//! state.feed_chars("c");
//! assert!(state.is_accepting());
//!
//! // "bcbc" is a suffix of "abcbc"
//! state.feed_chars("bc");
//! assert!(state.is_accepting());
//!
//! // "bcbcbc" is not a substring, much less a suffix of "abcbc"
//! state.feed_chars("bc");
//! assert!(!state.is_accepting() && state.is_nil());
//! ```
//!
//! ```rust
//! # #[cfg(feature = "trie")] {
//! use general_sam::{GeneralSam, Trie, BTreeTransTable};
//!
//! let mut trie = Trie::<BTreeTransTable<_>>::default();
//! trie.insert("hello".chars());
//! trie.insert("Chielo".chars());
//!
//! let sam = GeneralSam::<BTreeTransTable<_>>::from_trie(trie.get_root_state());
//!
//! assert!(sam.get_root_state().feed_chars("lo").is_accepting());
//! assert!(sam.get_root_state().feed_chars("ello").is_accepting());
//! assert!(sam.get_root_state().feed_chars("elo").is_accepting());
//!
//! assert!(!sam.get_root_state().feed_chars("el").is_accepting());
//! assert!(!sam.get_root_state().feed_chars("el").is_nil());
//!
//! assert!(!sam.get_root_state().feed_chars("bye").is_accepting());
//! assert!(sam.get_root_state().feed_chars("bye").is_nil());
