Struct ModuleDependencies 

pub struct ModuleDependencies { /* private fields */ }

The explicit Capability dependencies available during Module lifecycle.

Implementations

impl ModuleDependencies

pub fn bindings(&self) -> &[ModuleDependency]

Returns dependencies in the order materialized by the Resolved App Plan.

pub fn len(&self) -> usize

Returns the number of explicit dependencies.

pub fn is_empty(&self) -> bool

Returns whether this Module has no explicit dependencies.

pub fn invocation_context( &self, deadline: Option<Duration>, cancellation: CancellationToken, ) -> Result<InvocationContext, RuntimeFailure>

Creates a Kernel Invocation Context for work initiated by this Module.

The request identity and monotonic deadline come from the same Runtime Driver as the App. The context is still owned by the caller and its cancellation token remains explicit.

pub fn invocation_context_after( &self, timeout: Duration, cancellation: CancellationToken, ) -> Result<InvocationContext, RuntimeFailure>

Creates a Module Invocation Context with a Driver-relative deadline.

pub fn one<C: RequestCapability>( &self, ) -> Result<NativeRequestHandle<C>, RuntimeFailure>

Returns the one explicitly bound typed dependency.

pub fn optional<C: RequestCapability>( &self, ) -> Result<Option<NativeRequestHandle<C>>, RuntimeFailure>

Returns an optional explicitly bound typed dependency.

pub fn many<C: RequestCapability>( &self, ) -> Result<Vec<NativeRequestHandle<C>>, RuntimeFailure>

Returns all explicitly bound typed dependencies in resolved provider order.

pub fn one_stream<C: StreamCapability>( &self, ) -> Result<NativeStreamHandle<C>, RuntimeFailure>

Returns the one explicitly bound typed stream dependency.

pub fn optional_stream<C: StreamCapability>( &self, ) -> Result<Option<NativeStreamHandle<C>>, RuntimeFailure>

Returns an optional explicitly bound typed stream dependency.

pub fn many_stream<C: StreamCapability>( &self, ) -> Result<Vec<NativeStreamHandle<C>>, RuntimeFailure>

Returns all explicitly bound typed stream dependencies in Plan order.

pub fn many_event<C: EventCapability>( &self, ) -> Result<NativeEventHandle<C>, RuntimeFailure>

Returns one typed Event handle over every explicit binding in Plan order.

pub fn one_event<C: EventCapability>( &self, ) -> Result<NativeEventHandle<C>, RuntimeFailure>

Returns the one explicitly bound typed Event dependency.

pub fn optional_event<C: EventCapability>( &self, ) -> Result<Option<NativeEventHandle<C>>, RuntimeFailure>

Returns an optional explicitly bound typed Event dependency.

Trait Implementations

impl Clone for ModuleDependencies

fn clone(&self) -> ModuleDependencies

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModuleDependencies

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

Formats the value using the given formatter.

impl Default for ModuleDependencies

fn default() -> ModuleDependencies

Returns the “default value” for a type.
