Attribute Macro daft_extension 

#[daft_extension]

Generates the daft_module_magic entry point for a Daft extension module.

Place this attribute on a struct that implements DaftExtension. The macro generates the #[no_mangle] pub extern "C" fn daft_module_magic() symbol that Daft’s module loader resolves via dlopen.

Example

use daft_ext::prelude::*;

#[daft_extension]
struct MyExtension;

impl DaftExtension for MyExtension {
    fn install(session: &mut dyn DaftSession) {
        // register scalar functions here
    }
}
