Struct tvix_store::pathinfoservice::GRPCPathInfoService

source ·
pub struct GRPCPathInfoService<T> {
    instance_name: String,
    grpc_client: PathInfoServiceClient<T>,
}
Expand description

Connects to a (remote) tvix-store PathInfoService over gRPC.

Fields§

§instance_name: String§grpc_client: PathInfoServiceClient<T>

The internal reference to a gRPC client. Cloning it is cheap, and it internally handles concurrent requests.

Implementations§

source§

impl<T> GRPCPathInfoService<T>

source

pub fn from_client( instance_name: String, grpc_client: PathInfoServiceClient<T>, ) -> Self

construct a GRPCPathInfoService from a proto::path_info_service_client::PathInfoServiceClient. panics if called outside the context of a tokio runtime.
