The WebAssembly component tooling.

Modules

metadata

Definition for encoding of custom sections within core wasm modules of component-model related data.

Structs

ComponentEncoder

An encoder of components based on wit interface definitions.

Linker

Builder type for composing dynamic library modules into a component

OutputToString

Helper structure to help maintain an indentation level when printing source, modeled after the support in wit-bindgen-core. Indentation is set to two spaces.

WitPrinter

A utility for printing WebAssembly interface definitions to a string.

Enums

DecodedWasm

Result of the decode function.

StringEncoding

Supported string encoding formats.

TypeKind

Represents the different kinds of types that can be encountered while visiting a WIT file.

Traits

Output

Trait defining visitor methods driven by WitPrinter.

Functions

decode

Decodes an in-memory WebAssembly binary into a WIT Resolve and associated metadata.

decode_reader

Decode for incremental reading

dummy_moduledummy-module

Generate a dummy implementation core Wasm module for a given WIT document

embed_component_metadata

Embed component metadata in a buffer of bytes that contains a Wasm module

encode

Encodes the given package within resolve to a binary WebAssembly representation.

semver_checksemver-check

Tests whether new is a semver-compatible upgrade from the world prev.

targets

This function checks whether component_to_test correctly conforms to the world specified. It does so by instantiating a generated component that imports a component instance with the component type as described by the “target” world.
