Struct tower::balance::p2c::MakeBalanceLayer

source ·
pub struct MakeBalanceLayer<D, Req> { /* private fields */ }
Expand description

Construct load balancers (Balance) over dynamic service sets (Discover) produced by the “inner” service in response to requests coming from the “outer” service.

This construction may seem a little odd at first glance. This is not a layer that takes requests and produces responses in the traditional sense. Instead, it is more like MakeService in that it takes service descriptors (see Target on MakeService) and produces services. Since Balance spreads requests across a set of services, the inner service should produce a Discover, not just a single Service, given a service descriptor.

See the module-level documentation for details on load balancing.
