Module component

Expand description

Component module parsing, loading and execution

Structs§

Component: Pre-compiled component Component, which is cheapily-Cloneable
ComponentConfig: Component instance configuration
Ctx: Wasmtime Context for a component instance, with access to WASI context, HTTP context, and WRPC Invocation context. This is a low-level API and has to be paired with Component::new_with_linker.
CustomCtxComponent: The CustomCtxComponent is similar to Component, but it supports passing a custom context that implements the BaseCtx trait. This is useful for when you want to extend the context with additional host implementations or custom functionality.
Instance: Instantiated component
Limits: Component Environment Limits for more intricate resource control
MessagingGuestMessage0_3: A message originating from the guest

BaseCtx: The minimal implementation of a context that is required to run a component instance.
Bus: wasmcloud:bus/lattice@2.0.1 implementation
Bus1_0_0: wasmcloud:bus/lattice@1.0.0 implementation
Config: wasi:config/store implementation
Handler: A collection of traits that the host must implement
Identity: wasmcloud:identity/store implementation
InvocationErrorIntrospect: Implementations of this trait are able to introspect an error returned by wRPC invocations
Logging: wasi:logging/logging implementation
Messaging0_2: wasmcloud:messaging abstraction
Messaging0_3: wasmcloud:messaging abstraction
MessagingClient0_3: A connection to a message-exchange service (e.g., buffer, broker, etc.).
MessagingHostMessage0_3: A message with a binary payload and additional information
MinimalHandler: MinimalHandler represents the base traits that a handler must implement to be used with wasmcloud_runtime. It is a subset of the Handler trait, which includes many more traits for capability implementations when running in wasmCloud.
Secrets: wasmcloud:secrets implementation

claims_token: Extracts and validates claims contained within a WebAssembly binary, if present
from_string_map: Creates limits from a string-based key-value map.

InvocationStream: This represents a Stream of incoming invocations. Each item represents processing of a single invocation.
