Struct DylibArtifact

pub struct DylibArtifact { /* private fields */ }

A compiled Wasm module, ready to be instantiated.

Implementations

impl DylibArtifact

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

Check if the provided bytes look like DylibArtifact.

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( metadata: ModuleMetadata, dylib_path: PathBuf, ) -> Result<Self, CompileError>

Construct a DylibArtifact from component parts.

pub fn from_parts( engine_inner: &mut DylibEngineInner, metadata: ModuleMetadata, dylib_path: PathBuf, lib: Library, ) -> Result<Self, CompileError>

Construct a DylibArtifact from component parts.

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

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

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

Deserialize a DylibArtifact from bytes.

Safety

The bytes must represent a serialized WebAssembly module.

pub unsafe fn deserialize_from_file( engine: &DylibEngine, path: &Path, ) -> Result<Self, DeserializeError>

Deserialize a DylibArtifact from a file path.

Safety

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

pub unsafe fn deserialize_from_file_unchecked( engine: &DylibEngine, path: &Path, ) -> Result<Self, DeserializeError>

Deserialize a DylibArtifact from a file path (unchecked).

Safety

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

pub fn metadata(&self) -> &ModuleMetadata

Used in test deserialize metadata is correct
