Modules

• error
  Error types for interacting with a provider
• otel
• provider

Macros

• initialize_observability
  Initialize observability for a given provider with host-supplied data, via tracing.

Structs

• Context
  Context - message passing metadata used by wasmCloud Capability Providers
• HealthCheckRequest
  Re-export of types from wasmcloud_core
• HealthCheckResponse
  Re-export of types from wasmcloud_core
• HostData
  Re-export of types from wasmcloud_core initialization data for a capability provider
• InterfaceLinkDefinition
  Re-export of types from wasmcloud_core A link definition between a source and target component (component 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.
• LinkConfig
  Configuration of a link that is passed to a provider

Constants

• Provider
  Capability Provider handling of messages from host
• ProviderConfigUpdate
  Objects that can act as provider configuration updates
• ProviderInitConfig
  Configuration object is made available when a provider is started, to assist in init

Functions

• parse_wit_meta_from_operation
  Parse an sufficiently specified WIT operation/method into constituent parts.
• 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)
