Struct wasmer::Engine

pub struct Engine(_);

The engine type

Implementations

impl Engine

pub fn cloned(&self) -> Self

👎Deprecated since 3.2.0: engine.cloned() has been deprecated in favor of engine.clone()

Returns the Engine.

pub fn deterministic_id(&self) -> &str

Returns the deterministic id of this engine

pub fn new( compiler_config: Box<dyn CompilerConfig>, target: Target, features: Features ) -> Self

👎Deprecated since 3.2.0

Create a new Engine with the given config

pub fn headless() -> Self

Create a headless Engine Will be removed in 4.0 in favor of the NativeEngineExt trait

pub fn inner(&self) -> MutexGuard<'_, EngineInner>

👎Deprecated since 3.2.0

Get reference to EngineInner.

pub fn inner_mut(&self) -> MutexGuard<'_, EngineInner>

👎Deprecated since 3.2.0

Get mutable reference to EngineInner.

pub fn target(&self) -> &Target

Gets the target Will be removed in 4.0 in favor of the NativeEngineExt trait

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

👎Deprecated since 3.2.0

Register a signature

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

👎Deprecated since 3.2.0

Lookup a signature

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

👎Deprecated since 3.2.0

Validates a WebAssembly module

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

👎Deprecated since 3.2.0

Compile a WebAssembly binary

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

👎Deprecated since 3.2.0

Deserializes a WebAssembly module

Safety

The serialized content must represent a serialized WebAssembly module.

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

👎Deprecated since 3.2.0

Deserializes a WebAssembly module from a path

Safety

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

pub fn id(&self) -> &str

👎Deprecated since 3.2.0: Use Engine::deterministic_id()

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 set_tunables(&mut self, tunables: impl Tunables + Send + Sync + 'static)

Attach a Tunable to this engine Will be removed in 4.0 in favor of the NativeEngineExt trait

pub fn tunables(&self) -> &dyn Tunables

Get a reference to attached Tunable of this engine Will be removed in 4.0 in favor of the NativeEngineExt trait
