Struct DlModule

pub struct DlModule { /* private fields */ }

A Lucet module backed by a dynamically-loaded shared object.

Implementations

impl DlModule

pub fn load<P: AsRef<Path>>(so_path: P) -> Result<Arc<Self>, Error>

Create a module, loading code from a shared object on the filesystem.

pub fn load_and_verify<P: AsRef<Path>>( so_path: P, pk: PublicKey, ) -> Result<Arc<Self>, Error>

Create a module, loading code from a shared object on the filesystem and verifying it using a public key if one has been supplied.
