RequestScope

Struct RequestScope 

Source
pub struct RequestScope<'a> { /* private fields */ }
Expand description

Per-request dependency scope.

Implementations§

Source§

impl RequestScope<'_>

Source

pub fn resolve<T>(&self) -> Result<Arc<T>>
where T: Send + Sync + 'static,

Resolves a dependency in this request scope.

Source

pub fn inject<T>(&self) -> Result<Inject<T>>
where T: Send + Sync + 'static,

Resolves a typed dependency reference in this request scope.

Source

pub fn optional<T>(&self) -> Result<Optional<T>>
where T: Send + Sync + 'static,

Resolves an optional typed dependency reference in this request scope.

Missing providers become Optional::new(None), while registered providers that fail to construct still return their original error.

Source

pub fn scoped<T>(&self) -> Result<Scoped<T>>
where T: Send + Sync + 'static,

Resolves a request-scoped dependency wrapper in this request scope.

Source§

impl RequestScope<'static>

Source

pub fn from_shared_container(container: Arc<Container>) -> Self

Creates a request scope that owns a shared container handle.
