Expand description

A WebAssembly Universal Engine.

Implementations

source

impl UniversalEngine

source

pub fn headless() -> Self

Create a headless UniversalEngine

A headless engine is an engine without any compiler attached. This is useful for assuring a minimal runtime for running WebAssembly modules.

For example, for running in IoT devices where compilers are very expensive, or also to optimize startup speed.

Important

Headless engines can’t compile or validate any modules, they just take already processed Modules (via Module::serialize).
