Module wasmtime::component

Available on crate feature component-model only.

In-progress implementation of the WebAssembly component model

This module is a work-in-progress and currently represents an incomplete and probably buggy implementation of the component model.

Re-exports

• pub use self::types::ResourceType;
• pub use self::types::Type;

Modules

• types
  This module defines the Type type, representing the dynamic form of a component interface type.

Macros

• bindgen
  Generate bindings for a WIT package.
• flags

Structs

• Component
  A compiled WebAssembly Component.
• Enum
  Represents runtime enum values
• ExportInstance
  Description of the exports of a single instance.
• Exports
  Description of the exports of an Instance.
• Flags
  Represents runtime flag values
• Func
  A WebAssembly component function.
• Instance
  An instantiated component.
• InstancePre
  A “pre-instantiated” Instance which has all of its arguments already supplied and is ready to instantiate.
• Linker
  A type used to instantiate Components.
• LinkerInstance
  Structure representing an “instance” being defined within a linker.
• List
  Represents runtime list values
• OptionVal
  Represents runtime option values
• Record
  Represents runtime record values
• Resource
  A host-defined resource in the component model.
• ResourceAny
  Representation of a resource in the component model, either a guest-defined or a host-defined resource.
• ResourceImportIndex
  Index correlating a resource definition to the import path. This is assigned by Linker::resource and may be used to associate it to RuntimeImportIndex at a later stage
• ResourceTable
  The ResourceTable type maps a Resource<T> to its T.
• ResultVal
  Represents runtime result values
• Tuple
  Represents runtime tuple values
• TypedFunc
  A statically-typed version of Func which takes Params as input and returns Return.
• Variant
  Represents runtime variant values
• WasmList
  Representation of a list of values that are owned by a WebAssembly instance.
• WasmStr
  Representation of a string located in linear memory in a WebAssembly instance.

Enums

• ResourceTableError
  Errors returned by operations on ResourceTable
• Val
  Represents possible runtime values which a component function can either consume or produce

Traits

• ComponentNamedList
  A trait representing a static list of named types that can be passed to or returned from a TypedFunc.
• ComponentType
  A trait representing types which can be passed to and read from components with the canonical ABI.
• Lift
  Host types which can be created from the canonical ABI.
• Lower
  Host types which can be passed to WebAssembly components.
