pub struct OnChainExecution<T: Config>(/* private fields */);
Expand description
A simple on-chain implementation of the election provider trait.
This implements both ElectionProvider
and InstantElectionProvider
.
This type has some utilities to make it safe. Nonetheless, it should be used with utmost care. A
thoughtful value must be set as Config::Bounds
to ensure the size of the input is sensible.
