Implementations

Trait Implementations

impl Clone for KvNatsProvider

fn clone(&self) -> KvNatsProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for KvNatsProvider

fn default() -> KvNatsProvider

Returns the “default value” for a type.

impl Provider for KvNatsProvider

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 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 on_config_update( &self, update: impl ProviderConfigUpdate, ) -> impl Future<Output = Result<(), E>> + Send

Process a configuration update for 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
