pub fn duplicate( &self, id: u64, dest_id: u64, ) -> QueryResponseFut<CapabilityStoreDuplicateResult, DefaultFuchsiaResourceDialect>

Duplicates the capability with id to dest_id.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• ID_ALREADY_EXISTS if a capability with dest_id already exists in this store.
• NOT_DUPLICATABLE if id could not be duplicated.

pub fn drop( &self, id: u64, ) -> QueryResponseFut<CapabilityStoreDropResult, DefaultFuchsiaResourceDialect>

Drops the capability with id from this [CapabilityStore].

Errors:

pub fn export( &self, id: u64, ) -> QueryResponseFut<CapabilityStoreExportResult, DefaultFuchsiaResourceDialect>

Exports the capability with the client-assigned identifier id to capability. This operation removes the capability from the store. If this is not desired, [Duplicate] the capability first.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.

pub fn import( &self, id: u64, capability: Capability, ) -> QueryResponseFut<CapabilityStoreImportResult, DefaultFuchsiaResourceDialect>

Imports capability into this store with the client-assigned id.

Errors:

• ID_ALREADY_EXISTS if a capability with id already exists in this store.
• BAD_CAPABILITY if capability was not a valid Capability.

pub fn connector_create( &self, id: u64, receiver: ClientEnd<ReceiverMarker>, ) -> QueryResponseFut<CapabilityStoreConnectorCreateResult, DefaultFuchsiaResourceDialect>

Creates a Connector from a [Receiver]. Incoming connections to the Connector will be dispatched to this [Receiver].

Errors:

• ID_ALREADY_EXISTS if a capability with id already exists in this store.

pub fn connector_open( &self, id: u64, server_end: Channel, ) -> QueryResponseFut<CapabilityStoreConnectorOpenResult, DefaultFuchsiaResourceDialect>

If there is an error, it will be reported as a zx.Status epitaph on server_end.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• WRONG_TYPE if id was not a connector capability.

pub fn dir_connector_create( &self, id: u64, receiver: ClientEnd<DirReceiverMarker>, ) -> QueryResponseFut<CapabilityStoreDirConnectorCreateResult, DefaultFuchsiaResourceDialect>

pub fn dir_connector_open( &self, id: u64, server_end: ServerEnd<DirectoryMarker>, ) -> QueryResponseFut<CapabilityStoreDirConnectorOpenResult, DefaultFuchsiaResourceDialect>

Open a connection from the provided DirConnector capability that will be dispatched to the [DirReceiver] on the other end.

This method does not take Open/Open3 parameters such as flags or path. Clients that wish to specify these can get an initial connection from this method and call fuchsia.io/Directory.Open on it. See the [DirReceiver] documentation for more information about the expectations of the server side.

If there was an error making the connection, it will be reported as a zx.Status epitaph on server_end.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• WRONG_TYPE if id was not a connector capability.

pub fn dictionary_create( &self, id: u64, ) -> QueryResponseFut<CapabilityStoreDictionaryCreateResult, DefaultFuchsiaResourceDialect>

Creates a new empty dictionary in this [CapabilityStore] with client-assigned id.

Errors:

• ID_ALREADY_EXISTS if a capability with id already exists in this store.

pub fn dictionary_legacy_import( &self, id: u64, client_end: Channel, ) -> QueryResponseFut<CapabilityStoreDictionaryLegacyImportResult, DefaultFuchsiaResourceDialect>

This is a legacy API to support backward compatibility with APIs that take a [Dictionary] channel.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.

pub fn dictionary_insert( &self, id: u64, item: &DictionaryItem, ) -> QueryResponseFut<CapabilityStoreDictionaryInsertResult, DefaultFuchsiaResourceDialect>

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• WRONG_TYPE if id was not a dictionary.
• INVALID_KEY if item.key was invalid.
• ITEM_ALREADY_EXISTS if the dictionary already contains an item with item.key.

pub fn dictionary_get( &self, id: u64, key: &str, dest_id: u64, ) -> QueryResponseFut<CapabilityStoreDictionaryGetResult, DefaultFuchsiaResourceDialect>

Get a duplicate of a capability from the dictionary with id, which is loaded into dest_id.

Errors:

• ID_NOT_FOUND if id was not a recognized capability id in this store.
• ID_ALREADY_EXISTS if a capability with dest_id already exists in this store.
• WRONG_TYPE if id was not a dictionary.
• INVALID_KEY if item.key was invalid.
• ITEM_NOT_FOUND if the dictionary does not contain key.
• NOT_DUPLICATABLE if the capability could not be duplicated.

pub fn dictionary_remove( &self, id: u64, key: &str, dest_id: Option<&WrappedCapabilityId>, ) -> QueryResponseFut<CapabilityStoreDictionaryRemoveResult, DefaultFuchsiaResourceDialect>

Removes a key from the dictionary with id. If dest_id is present, loads the value into it, otherwise discards the value.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• ID_ALREADY_EXISTS if a capability with dest_id already exists in this store.
• WRONG_TYPE if id was not a dictionary.
• INVALID_KEY if key was invalid.
• ITEM_NOT_FOUND if the dictionary does not contain the key.

pub fn dictionary_copy( &self, id: u64, dest_id: u64, ) -> QueryResponseFut<CapabilityStoreDictionaryCopyResult, DefaultFuchsiaResourceDialect>

Create a new dictionary that contains a duplicate of all the entries in the dictionary with id, assigning dest_id to the new dictionary. The runtime of this method is linear in the number of top-level entries in the dictionary.

For example, if the dictionary contains nested dictionaries, the newly created dictionary will contain references to those same nested dictionaries because the entries are duplicated rather than deep-copied.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• ID_ALREADY_EXISTS if a capability with dest_id already exists in this store.
• WRONG_TYPE if id was not a dictionary.
• NOT_DUPLICATABLE if one of the capabilities in id could not be duplicated.

pub fn dictionary_keys( &self, id: u64, iterator: ServerEnd<DictionaryKeysIteratorMarker>, ) -> QueryResponseFut<CapabilityStoreDictionaryKeysResult, DefaultFuchsiaResourceDialect>

Enumerates the keys in the dictionary with id.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• WRONG_TYPE if id was not a dictionary.

pub fn dictionary_enumerate( &self, id: u64, iterator: ServerEnd<DictionaryEnumerateIteratorMarker>, ) -> QueryResponseFut<CapabilityStoreDictionaryEnumerateResult, DefaultFuchsiaResourceDialect>

Enumerates the items (keys and values) in the dictionary with id.

Creates a duplicate of each value (capability). If a value could not be duplicated, the value will be null.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• WRONG_TYPE if id was not a dictionary.

pub fn dictionary_drain( &self, id: u64, iterator: Option<ServerEnd<DictionaryDrainIteratorMarker>>, ) -> QueryResponseFut<CapabilityStoreDictionaryDrainResult, DefaultFuchsiaResourceDialect>

Removes all the entries in this dictionary, returning them in contents if provided. If contents is not provided, all the items are discarded without enumerating them.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• WRONG_TYPE if id was not a dictionary.
