Struct DependencyStore 

pub struct DependencyStore { /* private fields */ }

Type-indexed dependency container for runtime and tool contexts.

Implementations

impl DependencyStore

pub fn new() -> Self

Create an empty dependency store.

pub fn insert<T>(&mut self, value: T)

where T: Send + Sync + 'static,

Insert a dependency using its Rust type as the lookup key.

pub fn insert_arc<T>(&mut self, value: Arc<T>)

where T: Send + Sync + 'static,

Insert an already shared dependency using its Rust type as the lookup key.

pub fn insert_named<T>(&mut self, name: impl Into<String>, value: T)

where T: Send + Sync + 'static,

Insert a dependency with a caller-provided stable name.

The inserted name becomes the preferred typed lookup for T; older names remain available through named lookup.

pub fn insert_named_arc<T>(&mut self, name: impl Into<String>, value: Arc<T>)

where T: Send + Sync + 'static,

Insert an already shared dependency with a caller-provided stable name.

Replacing a preferred name with another type reindexes any remaining alias for the previous type instead of leaving a stale typed mapping.

pub fn get<T>(&self) -> Option<Arc<T>>

where T: Send + Sync + 'static,

Get a dependency by Rust type.

pub fn get_named<T>(&self, name: &str) -> Option<Arc<T>>

where T: Send + Sync + 'static,

Get a dependency by stable name.

pub fn subset(&self, names: &BTreeSet<String>) -> Self

Clone a dependency subset selected by stable names.

Typed lookup remains available when the selected name is not the source store’s preferred alias for that type. If several selected names contain the same type, the source store’s preferred alias wins when selected; otherwise stable name order determines the fallback alias.

pub fn extend(&mut self, other: Self)

Merge dependencies from another store, replacing matching stable names and typed lookups.

pub fn keys(&self) -> Vec<String>

Return all named dependency keys.

pub fn is_empty(&self) -> bool

Return whether the store has no dependencies.
