transport

Documentation

Overview

Package transport defines the network transport abstraction (client + codec) for the distributed backend. Concrete implementations (HTTP, gRPC, etc.) will satisfy the Client interface.

Types

type Client

type Client interface {
	Get(ctx context.Context, node string, key string) ([]byte, bool, error)
	Set(ctx context.Context, node string, key string, value []byte, expiration time.Duration, replicate bool) error
	Remove(ctx context.Context, node string, key string, replicate bool) error
	Health(ctx context.Context, node string) error
}

Client defines network transport operations needed by distributed backend. This abstracts over HTTP, gRPC, etc.

type Codec

type Codec interface {
	Marshal(v any) ([]byte, error)
	Unmarshal(data []byte, v any) error
}

Codec marshals/unmarshals values for transport (can reuse backend serializers).

type RPCError

type RPCError struct {
	Op   string
	Node string
	Err  error
}

RPCError represents a transport-level error (placeholder for richer classification).
