Struct State

Source

pub struct State<DB: Marker> { /* private fields */ }

Expand description

Application state that enables the Tx extractor.

State must be provided to Routers in order to use the Tx extractor, or else attempting to use the Router will not compile.

State is constructed via Tx::setup or Config::setup, which also return a middleware Layer. The state and the middleware together enable the Tx extractor to work.
