Struct NatsBlobstoreProvider 

pub struct NatsBlobstoreProvider { /* private fields */ }

NatsBlobstoreProvider holds the default NATS connection configuration and individual consumer components’ established NATS JetStream connections.

Implementations

Trait Implementations

impl Clone for NatsBlobstoreProvider

fn clone(&self) -> NatsBlobstoreProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for NatsBlobstoreProvider

fn default() -> NatsBlobstoreProvider

Returns the “default value” for a type.

impl Handler<Option<Context>> for NatsBlobstoreProvider

async fn get_container_data( &self, context: Option<Context>, id: ObjectId, start: u64, end: u64, ) -> Result<Result<(Pin<Box<dyn Stream<Item = Bytes> + Send>>, Pin<Box<dyn Future<Output = Result<(), String>> + Send>>), String>>

Retrieve data from an object in the specified NATS blobstore Container Optionally specify start and end byte offsets for partial reads

async fn list_container_objects( &self, context: Option<Context>, name: String, _offset: Option<u64>, _limit: Option<u64>, ) -> Result<Result<(Pin<Box<dyn Stream<Item = Vec<String>> + Send>>, Pin<Box<dyn Future<Output = Result<(), String>> + Send>>), String>>

Helper function to list all objects in a NATS blobstore container. This ensures consistent implementation across all functions that need to list objects. Delegates to the core implementation in blobstore.rs.

async fn create_container( &self, context: Option<Context>, name: String, ) -> Result<Result<(), String>>

async fn get_container_info( &self, context: Option<Context>, name: String, ) -> Result<Result<ContainerMetadata, String>>

async fn container_exists( &self, context: Option<Context>, name: String, ) -> Result<Result<bool, String>>

async fn write_container_data( &self, context: Option<Context>, id: ObjectId, data: Pin<Box<dyn Stream<Item = Bytes> + Send>>, ) -> Result<Result<Pin<Box<dyn Future<Output = Result<(), String>> + Send>>, String>>

async fn clear_container( &self, context: Option<Context>, name: String, ) -> Result<Result<(), String>>

async fn has_object( &self, context: Option<Context>, id: ObjectId, ) -> Result<Result<bool, String>>

async fn get_object_info( &self, context: Option<Context>, id: ObjectId, ) -> Result<Result<ObjectMetadata, String>>

async fn copy_object( &self, context: Option<Context>, source: ObjectId, destination: ObjectId, ) -> Result<Result<(), String>>

async fn move_object( &self, context: Option<Context>, source: ObjectId, destination: ObjectId, ) -> Result<Result<(), String>>

async fn delete_object( &self, context: Option<Context>, id: ObjectId, ) -> Result<Result<(), String>>

async fn delete_objects( &self, context: Option<Context>, name: String, objects: Vec<String>, ) -> Result<Result<(), String>>

impl Provider for NatsBlobstoreProvider

Handle provider control commands

async fn receive_link_config_as_target( &self, link_config: LinkConfig<'_>, ) -> Result<()>

Provider should perform any operations needed for a new link, including setting up per-component resources, and checking authorization. If the link is allowed, return true, otherwise return false to deny the link.

async fn delete_link_as_target(&self, info: impl LinkDeleteInfo) -> Result<()>

Provider should perform any operations needed for a link deletion, including cleaning up per-component resources.

async fn on_config_update( &self, update: impl ProviderConfigUpdate, ) -> Result<()>

Provider should perform any operations needed for configuration updates, including cleaning up invalidated link resources.

async fn shutdown(&self) -> Result<()>

Handle shutdown request by closing all connections

fn init( &self, init_config: impl ProviderInitConfig, ) -> impl Future<Output = Result<(), E>> + Send

Initialize the provider

fn receive_link_config_as_source( &self, config: LinkConfig<'_>, ) -> impl Future<Output = Result<(), E>> + Send

Receive and handle a link that has been established on the lattice where this provider is the source.

fn delete_link_as_source( &self, _info: impl LinkDeleteInfo, ) -> impl Future<Output = Result<(), E>> + Send

Notify the provider that the link is dropped where the provider is the source

fn health_request( &self, _arg: &HealthCheckRequest, ) -> impl Future<Output = Result<HealthCheckResponse, E>> + Send

Perform health check. Called at regular intervals by host Default implementation always returns healthy
