agent/agent library

Classes

Actor
An actor base class. An actor is an object containing only functions that will return a promise. These functions are derived from the IDL definition.
ActorConfig
Configuration that can be passed to customize the Actor behaviour.
ActorMetadata
Internal metadata for actors. It's an enhanced version of ActorConfig with some fields marked as required (as they are defaulted) and canisterId as a Principal type.
ActorMethod
Agent
An Agent able to make calls and queries to a Replica.
AgentFactory
AnonymousIdentity
AssetActor
Try to understand how idl can be transformed.
