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
