Struct ImportHandle 

pub struct ImportHandle { /* private fields */ }

A lazy, composition-bound handle for one declared import slot.

Clones retain the slot and ordered capability identities and observe the same eventual target seal. Until sealed, calls fail as unavailable.

Implementations

impl ImportHandle

pub fn slot_id(&self) -> &BoxId

Returns this handle’s declared import-slot identity.

pub fn capabilities(&self) -> &[CapabilityId]

Returns allowed capability identities in declaration order.

pub fn call<'a>( &'a self, capability: &'a CapabilityId, context: CallContext, input: SlotValue, ) -> Pin<Box<dyn Future<Output = Result<SlotValue, ErasedCallError>> + Send + 'a>>

Invokes a declared capability through the sealed import target.

Calls fail before provider invocation when the handle is unsealed, the capability is undeclared, or the supplied deadline is already expired, in that order. Provider panics are contained by the contract dispatch boundary. The returned future is Send.

Trait Implementations

impl Clone for ImportHandle

fn clone(&self) -> ImportHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.
