waphite

waphite (like "graphite") is a crate for executing WebAssembly

Usage

Add the following to your Cargo.toml:

[dependencies]
waphite = "0.1"

Examples

Basic Import:

letbytes=include_bytes!("add.wasm");letinstance=waphite::instantiate::<Contiguous,()>(bytes,vec![],()).expect("Failed to import `add.wasm`");leta: u8 =instance.call("add_two",&[4.into()]).unwrap()[0].into();assert_eq!(a,6);

Features

By default, the instance, memory, stacktrace, and helper_macros features are all enabled. Disabling default features leaves this crate entirely empty, allowing you to get only the pieces you need. For example, if you just need WASM memory, then you can enable only the memory feature.

List of all default features (and their dependencies):

• memory - Enables the memory module.
• wasm_value - Enables the WasmValue type.
• instance - (requires memory and wasm_value) Enables the WasmInstance type and everything related to it.
• helper_macros - (requires instance) Enables the exports and call macros.
• stacktrace - (requires instance) Enables the WasmStacktrace type.

List of all non-default features

• experimental - Enables the experimental module.
• call_async - Enables various async ways of calling WASM functions

To get the most bare-bones version of this crate that can still execute WASM, enabling the engine feature is all you need to do.
