• out_dir - The target directory to save the generated shared library file.

Error

If fail to compile, then an error is returned.

pub fn compile_from_bytes( &self, bytes: impl AsRef<[u8]>, filename: impl AsRef<str>, out_dir: impl AsRef<Path>, ) -> WasmEdgeResult<PathBuf>

Compiles the given wasm bytes into a shared library file (*.so in Linux, *.dylib in macOS, or *.dll in Windows). The file path of the generated shared library file will be returned if the method works successfully.

Argument

• bytes - A in-memory WASM bytes.

• filename - The filename of the generated shared library file.

• out_dir - The target directory to save the generated shared library file.
