Struct DirectoryResolvingClient

pub struct DirectoryResolvingClient<C> { /* private fields */ }

Expand description

Self-healing REST transport that resolves its endpoint from the directory.

Generic over the concrete generated client C (e.g. PaymentApiRestClient). The generated <Trait>ResolvingClient wraps one of these and delegates each trait method through DirectoryResolvingClient::resolved.

Implementations§

Source §

impl<C> DirectoryResolvingClient<C>
where C: Send + Sync + 'static,

Source

pub fn new( resolver: Arc<dyn EndpointResolver>, from_gear: impl Into<String>, tuning: ClientTuning, build: impl Fn(ClientConfig) -> Result<C, TransportError> + Send + Sync + 'static, ) -> DirectoryResolvingClient<C>

Construct a resolving client.

resolver — resolves the provider gear name to a live endpoint.
from_gear — the logical provider gear name to resolve.
tuning — timeout/retry/reconnect overrides applied to each built client.
build — constructs the concrete client C from a ClientConfig (the generated C::new(config), mapping its error into TransportError).

Source

pub fn from_gear(&self) -> &str

The logical provider gear name this client resolves against.

Source

pub async fn resolved(&self) -> Result<Arc<C>, TransportError>

Resolve (or reuse) the underlying client for the current endpoint.

Re-resolves the directory on every call so a moved or vanished provider is observed immediately; the built client is cached and reused while the endpoint is unchanged. Returns TransportError::Unresolved when no live instance is registered.

§Errors

TransportError::Unresolved if the directory has no live endpoint.
Whatever build returns if constructing the client fails.
