Struct NamespaceRegistry 

pub struct NamespaceRegistry<V> { /* private fields */ }

Implementations

impl<V: Clone> NamespaceRegistry<V>

pub fn new(initial: impl AsRef<str>) -> Self

pub fn current(&self) -> Namespace<V>

pub fn find(&self, name: impl AsRef<str>) -> Option<Namespace<V>>

pub fn find_or_create(&self, name: impl AsRef<str>) -> Namespace<V>

pub fn set_current(&self, name: impl AsRef<str>) -> Namespace<V>

pub fn all(&self) -> Vec<Namespace<V>>

pub fn known_names(&self) -> Vec<Symbol>

Returns every namespace known either as a materialized namespace or as a discoverable module with load state. Catalog-backed modules can therefore be inspected before a Namespace value exists.

pub fn load_state(&self, name: impl AsRef<str>) -> Option<NamespaceLoadState>

pub fn set_load_state(&self, name: impl AsRef<str>, state: NamespaceLoadState)

pub fn clear_load_state(&self, name: impl AsRef<str>)

pub fn load_failure(&self, name: impl AsRef<str>) -> Option<String>
