Struct ModuleRef 

pub struct ModuleRef { /* private fields */ }

Runtime provider container. This is Boot’s Rust equivalent of Nest’s ModuleRef.

Implementations

impl ModuleRef

pub fn new() -> Self

pub fn request_scope(&self) -> Self

pub fn register(&self, definition: ProviderDefinition) -> Result<()>

pub async fn register_async(&self, definition: ProviderDefinition) -> Result<()>

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

where T: Send + Sync + 'static,

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

where T: Send + Sync + 'static,

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

where T: Send + Sync + 'static,

pub fn get_named<T>(&self, token: &str) -> Result<Arc<T>>

where T: Send + Sync + 'static,

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

where T: Send + Sync + 'static,

pub fn get_optional_named<T>(&self, token: &str) -> Result<Option<Arc<T>>>

where T: Send + Sync + 'static,

pub fn provider_ref<T>(&self) -> ProviderRef<T>

where T: Send + Sync + 'static,

Create a lazy provider handle for a typed dependency.

pub fn named_provider_ref<T>(&self, token: &str) -> ProviderRef<T>

where T: Send + Sync + 'static,

Create a lazy provider handle for a named dependency.

pub fn optional_provider_ref<T>(&self) -> Result<Option<ProviderRef<T>>>

where T: Send + Sync + 'static,

Create a lazy provider handle only when the typed dependency is visible.

pub fn optional_named_provider_ref<T>( &self, token: &str, ) -> Result<Option<ProviderRef<T>>>

where T: Send + Sync + 'static,

Create a lazy provider handle only when the named dependency is visible.

pub fn resolve<T>(&self) -> Result<Arc<T>>

where T: Send + Sync + 'static,

Resolve a typed provider in a fresh resolution context.

This mirrors Nest’s ModuleRef.resolve(...): singleton providers reuse their application instance, while request-scoped dependencies share one temporary context for this resolution and transient providers are rebuilt.

pub fn resolve_named<T>(&self, token: &str) -> Result<Arc<T>>

where T: Send + Sync + 'static,

Resolve a named provider in a fresh resolution context.

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

where T: Send + Sync + 'static,

Resolve a typed provider in a fresh resolution context when it exists.

pub fn resolve_optional_named<T>(&self, token: &str) -> Result<Option<Arc<T>>>

where T: Send + Sync + 'static,

Resolve a named provider in a fresh resolution context when it exists.

pub fn create<T>(&self) -> Result<T>

where T: FromModuleRef,

Create an injectable value without registering it in the provider graph.

pub fn create_arc<T>(&self) -> Result<Arc<T>>

where T: FromModuleRef,

Create an injectable Arc<T> without registering it in the provider graph.

pub fn contains(&self, token: &ProviderToken) -> Result<bool>

pub fn contains_provider<T>(&self) -> Result<bool>

where T: Send + Sync + 'static,

pub fn contains_named(&self, token: &str) -> Result<bool>

pub fn tokens(&self) -> Result<Vec<ProviderToken>>
