Struct AlphabetRegistry 

pub struct AlphabetRegistry<A: SerialAlphabet> { /* private fields */ }

A same-type alphabet registry that rejects duplicate stable identities.

The registry is deliberately a value-layer helper, not a global singleton.

Implementations

impl<A: SerialAlphabet> AlphabetRegistry<A>

pub fn new() -> Self

Constructs an empty registry.

pub fn insert(&mut self, alphabet: A) -> Result<(), AlphabetError>

Validates and inserts an alphabet, rejecting an id already in the registry.

pub fn get(&self, id: &AlphabetId) -> Option<&A>

Looks up an alphabet by stable identity.

pub fn len(&self) -> usize

Returns the number of registered alphabets.

pub fn is_empty(&self) -> bool

Returns whether no alphabets are registered.
