Struct Registry 

pub struct Registry<T: Registrable> { /* private fields */ }

A generic, owned registry mapping string keys to &'static T references.

Registries are immutable after construction — no Mutex needed. Use auto_discover() to populate from inventory, or new() + register() for manual construction (useful in tests).

Implementations

impl<T: Registrable> Registry<T>

pub fn new() -> Self

Create an empty registry.

pub fn auto_discover() -> Self

where T: Collect,

Populate from all inventory::submit!-ed items of type T.

pub fn register(&mut self, item: &'static T)

Insert a descriptor. If a descriptor with the same key already exists, it is replaced (last-write-wins).

pub fn get(&self, key: &str) -> Option<&'static T>

Look up an item by registry key.

pub fn list(&self) -> Vec<&str>

Returns all registered keys in arbitrary order.

pub fn len(&self) -> usize

Return the number of registered items.

pub fn is_empty(&self) -> bool

Return true when no items are registered.

pub fn iter(&self) -> impl Iterator<Item = &'static T> + '_

Iterates over all registered descriptors in arbitrary order.

Trait Implementations

impl<T: Registrable> Clone for Registry<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Registrable> Debug for Registry<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Registrable> Default for Registry<T>

fn default() -> Self

Returns the “default value” for a type.
