[][src]Struct wasmer_engine_native::NativeEngine

pub struct NativeEngine { /* fields omitted */ }

A WebAssembly Native Engine.


impl NativeEngine[src]

pub fn headless() -> Self[src]

Create a headless NativeEngine

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.


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

pub fn set_deterministic_prefixer<F>(&mut self, prefixer: F) where
    F: Fn(&[u8]) -> String + Send + 'static, 

Sets a prefixer for the wasm module, so we can avoid any collisions in the exported function names on the generated shared object.

This, allows us to rather than have functions named wasmer_function_1 to be named wasmer_function_PREFIX_1.


This prefixer function should be deterministic, so the compilation remains deterministic.

Compile a WebAssembly binary (it will fail because the compiler flag is disabled).

pub unsafe fn deserialize(
    bytes: &[u8]
) -> Result<Arc<dyn Artifact>, DeserializeError>

Deserializes a WebAssembly module (binary content of a Shared Object file)

pub unsafe fn deserialize_from_file(

) -> Result<Arc<dyn Artifact>, DeserializeError>

Deserializes a WebAssembly module from a path It should point to a Shared Object file generated by this engine.
