Struct Api

pub struct Api { /* private fields */ }

Object that allows interaction with a TAPLE node.

It has methods to perform all available read and write operations.

Implementations

impl Api

pub fn new( peer_id: PeerId, controller_id: String, public_key: Vec<u8>, sender: SenderEnd<APICommands, ApiResponses>, ) -> Self

pub fn peer_id(&self) -> &PeerId

pub fn controller_id(&self) -> &String

pub fn public_key(&self) -> &Vec<u8>

pub async fn get_request( &self, request_id: DigestIdentifier, ) -> Result<TapleRequest, ApiError>

pub async fn external_request( &self, event_request: Signed<EventRequest>, ) -> Result<DigestIdentifier, ApiError>

Allows to make a request to the node from an external Invoker

pub async fn get_subjects( &self, namespace: String, from: Option<String>, quantity: Option<i64>, ) -> Result<Vec<SubjectData>, ApiError>

Allows to get all subjects that are known to the current node, regardless of their governance. Paging can be performed using the optional arguments from and quantity. Regarding the first one, note that it admits negative values, in which case the paging is performed in the opposite direction starting from the end of the collection. Note that this method also returns the subjects that model governance.

Possible errors

• [ApiError::InternalError] if an internal error occurred during the execution of the operation.

pub async fn get_subjects_by_governance( &self, governance_id: DigestIdentifier, from: Option<String>, quantity: Option<i64>, ) -> Result<Vec<SubjectData>, ApiError>

pub async fn get_governances( &self, namespace: String, from: Option<String>, quantity: Option<i64>, ) -> Result<Vec<SubjectData>, ApiError>

It allows to obtain all the subjects that model existing governance in the node.

Possible errors

• [ApiError::InternalError] if an internal error occurred during the execution of the operation.

pub async fn get_event( &self, subject_id: DigestIdentifier, sn: u64, ) -> Result<Signed<Event>, ApiError>

pub async fn get_events( &self, subject_id: DigestIdentifier, from: Option<i64>, quantity: Option<i64>, ) -> Result<Vec<Signed<Event>>, ApiError>

Allows to obtain events from a specific subject previously existing in the node. Paging can be performed by means of the optional arguments from and quantity. Regarding the former, it should be noted that negative values are allowed, in which case the paging is performed in the opposite direction starting from the end of the string.

Possible errors

• ApiError::InvalidParameters if the specified subject identifier does not match a valid DigestIdentifier.

pub async fn get_subject( &self, subject_id: DigestIdentifier, ) -> Result<SubjectData, ApiError>

Allows to obtain a specified subject by specifying its identifier.

Possible errors

• ApiError::InvalidParameters if the specified identifier does not match a valid DigestIdentifier.
• ApiError::NotFound if the subject does not exist.

pub async fn add_preauthorize_subject( &self, subject_id: &DigestIdentifier, providers: &HashSet<KeyIdentifier>, ) -> Result<(), ApiError>

pub async fn get_all_allowed_subjects_and_providers( &self, from: Option<String>, quantity: Option<i64>, ) -> Result<Vec<(DigestIdentifier, HashSet<KeyIdentifier>)>, ApiError>

pub async fn add_keys( &self, derivator: KeyDerivator, ) -> Result<KeyIdentifier, ApiError>

pub async fn get_validation_proof( &self, subject_id: DigestIdentifier, ) -> Result<(HashSet<Signature>, ValidationProof), ApiError>

pub async fn get_governance_subjects( &self, governance_id: DigestIdentifier, from: Option<String>, quantity: Option<i64>, ) -> Result<Vec<SubjectData>, ApiError>
