Implementations

source

impl DylibArtifact

source

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

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

source

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

Get the default extension when serializing this artifact

source

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

Construct a DylibArtifact from component parts.

source

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

Construct a DylibArtifact from component parts.

source

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

source

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.

source

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.

source

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.

source

pub fn metadata(&self) -> &ModuleMetadata

Used in test deserialize metadata is correct
