Ref

diskann_benchmark_runner::dispatcher

Struct Ref

pub struct Ref<T: ?Sized + 'static>(/* private fields */);

Expand description

Allow references to cross dispatcher boundaries as shown in the following example:

use diskann_benchmark_runner::dispatcher::{Dispatcher1, Ref};

let mut d = Dispatcher1::<*const f32, Ref<[f32]>>::new();
d.register::<_, Ref<[f32]>>("method", |data: &[f32]| data.as_ptr());

let v = vec![1.0, 2.0];
assert_eq!(d.call(&v), Some(v.as_ptr()));
