Struct lucet_runtime_internals::module::DlModule

pub struct DlModule { /* fields omitted */ }

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

Methods

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.
