Tezos_raw_protocol_017_PtNairob.Delegate_samplerThis module draws random values for a cycle based on the Seed_repr.seed associated that cycle. These random values are:
This module is responsible for maintaining the table Storage.Delegate_sampler_state.

Tezos_protocol_environment_017_PtNairob.Lwt.tParticipation slots potentially associated to accounts. The accounts that didn't place a deposit will be excluded from this list. This function should only be used to compute the deposits to freeze or initialize the protocol while stitching. RPCs can use this function to predict an approximation of long term future slot allocations. It shouldn't be used in the baker.

Tezos_protocol_environment_017_PtNairob.Lwt.tload_sampler_for_cycle ctxt cycle caches the seeded stake sampler for cycle in ctxt. If the sampler was already cached, then ctxt is returned unchanged.
This function has the same effect on ctxt as slot_owner and baking_rights_owner.

Tezos_protocol_environment_017_PtNairob.Lwt.tcompute_snapshot_index ctxt cycle max_snapshot_index Returns the index of the selected snapshot for the cycle passed as argument, and for the max index of snapshots taken so far, max_snapshot_index (see Stake_storage.max_snapshot_index.
