README
dynosaur lets you use dynamic dispatch on traits with async fn and
methods returning impl Trait.
#[dynosaur::dynosaur(DynNext)]
trait Next {
type Item;
async fn next(&mut self) -> Self::Item;
}
The macro above generates a type called DynNext which can be used like this:
async fn dyn_dispatch(iter: &mut DynNext<'_, i32>) {
while let Some(item) = iter.next().await {
println!("- {item}");
}
}
let a = [1, 2, 3];
dyn_dispatch(DynNext::from_mut(&mut a.into_iter())).await;
The general rule is that anywhere you would write dyn Trait (which would
result in a compiler error), you instead write DynTrait.
Methods returning impl Trait box their return types when dispatched
dynamically, but not when dispatched statically.
