    // Required methods
    fn register(
        &self,
        sandbox: &mut UninitializedSandbox,
        name: &str,

    ) -> Result<()>;
}

Trait for registering a host function with zero parameters.

Required Methods

fn register(&self, sandbox: &mut UninitializedSandbox, name: &str) -> Result<()>

Register the host function with the given name in the sandbox.

fn register_with_extra_allowed_syscalls( &self, sandbox: &mut UninitializedSandbox, name: &str, extra_allowed_syscalls: Vec<ExtraAllowedSyscall>, ) -> Result<()>

Register the host function with the given name in the sandbox, allowing extra syscalls.
