Expand description

An Artifact is the product that the Engine implementation produce and use.

The Artifact contains the compiled data for a given module as well as extra information needed to run the module at runtime, such as ModuleInfo and Features.

Required Methods§

Source

fn module(&self) -> Arc<ModuleInfo>

Return a reference-counted pointer to the module

Source

fn module_ref(&self) -> &ModuleInfo

Return a pointer to a module.

Source

fn module_mut(&mut self) -> Option<&mut ModuleInfo>

Gets a mutable reference to the info.

Note: this will return None if the module is already instantiated.

Source

fn features(&self) -> &Features

Returns the features for this Artifact

Source

fn cpu_features(&self) -> EnumSet<CpuFeature>

Returns the CPU features for this Artifact

Source

fn memory_styles(&self) -> &PrimaryMap<MemoryIndex, MemoryStyle>

Returns the memory styles associated with this Artifact.

Source

fn table_styles(&self) -> &PrimaryMap<TableIndex, TableStyle>

Returns the table plans associated with this Artifact.

Source

fn data_initializers(&self) -> &[OwnedDataInitializer]

Returns data initializers to pass to InstanceHandle::initialize

Source

fn serialize(&self) -> Result<Vec<u8>, SerializeError>

Serializes an artifact into bytes

Provided Methods§

Source

fn serialize_to_file(&self, path: &Path) -> Result<(), SerializeError>

Serializes an artifact into a file path

Implementations§

Source§

impl dyn ArtifactCreate

Source

pub fn downcast_ref<T>(&self) -> Option<&T>
where T: 'static,

Try to downcast the artifact into a given type.

Source

pub fn downcast_mut<T>(&mut self) -> Option<&mut T>
where T: 'static,

Try to downcast the artifact into a given type mutably.
