LayerAdapter

rama::utils::tower

Struct LayerAdapter 

pub struct LayerAdapter<L> { /* private fields */ }
Available on crate feature tower only.
Expand description

Adapter to use a tower::Layer-tower::Service as a rama::Layer-rama::Service.

The produced tower::Service will be wrapped by a LayerAdapterService making it a fully compatible rama::Service ready to be plugged into a rama stack.

Note that you should use ServiceAdapter or SharedServiceAdapter for non-layer services.

Implementations§

pub fn new(layer: L) -> LayerAdapter<L>
