}

A unimplemented Wasmer Engine.

This trait is used by implementors to implement custom engines such as: JIT or Native.

The product that an Engine produces and consumes is the Artifact.

Required methods

pub fn target(&self) -> &Target[src]

Gets the target

pub fn register_signature(
    &self,
    func_type: &FunctionType
) -> VMSharedSignatureIndex[src]

Register a signature

pub fn lookup_signature(
    &self,
    sig: VMSharedSignatureIndex
) -> Option<FunctionType>[src]

Lookup a signature

pub fn validate(&self, binary: &[u8]) -> Result<(), CompileError>[src]

Validates a WebAssembly module

pub fn compile(
    &self,
    binary: &[u8],
    tunables: &dyn Tunables
) -> Result<Arc<dyn Artifact>, CompileError>[src]

Compile a WebAssembly binary

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

Deserializes a WebAssembly module

Safety

The serialized content must represent a serialized WebAssembly module.

pub fn id(&self) -> &EngineId[src]

A unique identifier for this object.

This exists to allow us to compare two Engines for equality. Otherwise, comparing two trait objects unsafely relies on implementation details of trait representation.

pub fn cloned(&self) -> Arc<dyn Engine + Send + Sync>[src]

Clone the engine

Provided methods

pub unsafe fn deserialize_from_file(
    &self,
    file_ref: &Path
) -> Result<Arc<dyn Artifact>, DeserializeError>[src]

Deserializes a WebAssembly module from a path

Safety

The file's content must represent a serialized WebAssembly module.
