Modules

• error
  Error types for interacting with a provider
• provider

Structs

• Context
  Context - message passing metadata used by wasmhost Actors and Capability Providers
• HealthCheckRequest
  Re-export of types from wasmcloud_core
• HealthCheckResponse
  Re-export of types from wasmcloud_core
• InterfaceLinkDefinition
  Re-export of types from wasmcloud_core A link definition between a source and target component (actor or provider) on a given interface. An InterfaceLinkDefinition connects one component’s import to another component’s export, specifying the configuration each component needs in order to execute the request, and represents an operator’s intent to allow the source to invoke the target.
• WasmCloudEntity
  Re-export of types from wasmcloud_core

Constants

• DEFAULT_RPC_TIMEOUT_MILLIS
  The default timeout for a request to the lattice, in milliseconds
• URL_SCHEME

Traits

• LinkConfig
  Configuration of a link that is passed to a provider
• Provider
  The super trait containing all necessary traits for a provider
• ProviderHandler
  CapabilityProvider handling of messages from host
• WrpcDispatch
  todo: invert this so that the provider takes the wrpc_transport::Client and then hooks up it’s own handlers Handler for dispatching invocations that come via wRPC
• WrpcNats
  A trait for providers that are powered by WIT contracts and communicate with wRPC

Functions

• parse_wit_meta_from_operation
  Parse an sufficiently specified WIT operation/method into constituent parts.
• rpc_topic
  Returns the rpc topic (subject) name for sending to an actor or provider. A provider entity must have the public_key and link_name fields filled in. An actor entity must have a public_key and an empty link_name.
• url
  Generates a fully qualified wasmbus URL for use in wascap claims. The optional method parameter is used for generating URLs for targets being invoked
• with_connection_event_logging
  helper method to add logging to a nats connection. Logs disconnection (warn level), reconnection (info level), error (error), slow consumer, and lame duck(warn) events.

Type Aliases

• WitFunction
  Re-export of types from wasmcloud_core A WIT function (ex. get in wasi:keyvalue/readwrite.get)
• WitInterface
  Re-export of types from wasmcloud_core WIT interface for a given operation (ex. readwrite in wasi:keyvalue/readwrite.get)
• WitNamespace
  Re-export of types from wasmcloud_core WIT namespace for a given operation (ex. wasi in wasi:keyvalue/readwrite.get)
• WitPackage
  Re-export of types from wasmcloud_core WIT package for a given operation (ex. keyvalue in wasi:keyvalue/readwrite.get)
• WorldKeyName
  Human readable name of a [wit_parser::WorldKey] which includes interface ID if necessary see: https://docs.rs/wit-parser/latest/wit_parser/struct.Resolve.html#method.name_world_key
• WrpcInvocationLookup
• WrpcNatsSubject
  A NATS subject which is used for wRPC, normally of the shape <lattice>.<target id>.wrpc.0.0.1.<interface>.<operation>
