KeyHashRouter

Struct KeyHashRouter

pub struct KeyHashRouter;

Expand description

Default router: key hash modulo shards, falling back to the source partition for keyless records (keeps a partition’s keyless records together and the distribution stable).

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<U> As for U

fn as_<T>(self) -> T
