Trait CapabilityRef 

pub trait CapabilityRef<'a>: Sized {
    // Required methods
    fn from_store(store: &'a CapabilityStore, id: CapabilityId) -> Self;
    fn store(&self) -> &'a CapabilityStore;
    fn id(&self) -> CapabilityId;

    // Provided methods
    fn duplicate(&'a self) -> impl Future<Output = Result<Self, Error>> { ... }
    fn drop(self) -> impl Future<Output = Result<(), Error>> { ... }
    fn export<T>(self) -> impl Future<Output = Result<T, Error>>
       where T: Importable<'a, Ref = Self> { ... }
}

A reference to a fsandbox::Capability stored in a repository held by the component framework.

This reference represents a capability of an unconfirmed type. Specify type parameters on export() methods to derive the type.

Required Methods

fn from_store(store: &'a CapabilityStore, id: CapabilityId) -> Self

Create a CapabilityRef referencing the given store and id.

Warning: If the capability stored in the store at the given key is not of type T, the type mismatch will only become apparent when attempting to call CapabilityRef::export or call type-specific methods on it.

fn store(&self) -> &'a CapabilityStore

Return a reference to the store containing this Capability.

fn id(&self) -> CapabilityId

Return the identifier for this Capability.

Provided Methods

fn duplicate(&'a self) -> impl Future<Output = Result<Self, Error>>

Duplicates the capability referenced by this ref, returning a new ref to the duplicated capability.

fn drop(self) -> impl Future<Output = Result<(), Error>>

Drop the referenced Capability held by the component framework runtime.

fn export<T>(self) -> impl Future<Output = Result<T, Error>>

where T: Importable<'a, Ref = Self>,

Extract the value of the referenced Capability and remove it from the component framework runtime.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
