Struct DynamicallyLinkedFileExtPlugin

pub struct DynamicallyLinkedFileExtPlugin {
    pub handle: ManuallyDrop<Box<dyn FileExtPlugin>>,
    pub library: ManuallyDrop<Library>,
}

This struct represents a dynamically linked Plugin. It loads the plugin from a shared library at runtime, storing the handle as a Box<dyn FileExtPlugin>. It’s really important to store the library as well, because once the library is dropped the handle will be invalid.

While for the Node struct we don’t care about the order of the library and the handle, because by design the node will be dropped before the library, it’s not the case here. And so we need either to use ManuallyDrop or to order the fields in a way that the library is dropped last.

Fields

handle: ManuallyDrop<Box<dyn FileExtPlugin>>

library: ManuallyDrop<Library>

Implementations

impl DynamicallyLinkedFileExtPlugin

pub fn new( handle: Box<dyn FileExtPlugin>, library: Library, ) -> DynamicallyLinkedFileExtPlugin
