Struct ObjectFileArtifact

pub struct ObjectFileArtifact { /* private fields */ }

A compiled wasm module, ready to be instantiated.

Implementations

impl ObjectFileArtifact

pub fn is_deserializable(bytes: &[u8]) -> bool

Check if the provided bytes look like ObjectFileArtifact.

This means, if the bytes look like a shared object file in the target system.

pub fn get_default_extension(triple: &Triple) -> &'static str

Get the default extension when serializing this artifact

pub fn from_parts_crosscompiled( engine_inner: &mut ObjectFileEngineInner, metadata: ModuleMetadata, module_bytes: Vec<u8>, metadata_length: usize, ) -> Result<Self, CompileError>

Construct a ObjectFileArtifact from component parts.

pub fn new( _engine: &ObjectFileEngine, _data: &[u8], ) -> Result<Self, CompileError>

Compile a data buffer into a ObjectFileArtifact, which may then be instantiated.

pub unsafe fn deserialize( engine: &ObjectFileEngine, bytes: &[u8], ) -> Result<Self, DeserializeError>

Deserialize a ObjectFileArtifact from bytes.

Safety

The bytes must represent a serialized WebAssembly module.

pub fn symbol_registry(&self) -> &dyn SymbolRegistry

Get the SymbolRegistry used to generate the names used in the Artifact.

pub fn metadata_length(&self) -> usize

The length in bytes of the metadata in the serialized output.
