Module Protocol_levels represents an associative map of protocol levels to corresponding blocks which supposedly activate new protocols, that is to say blocks that acknowledge a protocol change in the next block.

type protocol_info = {

protocol : Tezos_base.TzPervasives.Protocol_hash.t;
activation_block : block_descriptor;
expect_predecessor_context : bool;

}

The type for protocol info.

expect_predecessor_context is a flag which reflects what is referenced by the context hash of a block, depending on its protocol. If the flag is true, the block contains the predecessors context (context before the application of the block). Otherwise, it contains the resulting context hash of the application of the block. An activation block refers to a block which activated a new protocol N+1. Thus, the block header related to that activation block will have a protocol level which differs from its predecessor. As this block aims to activate a new protocol, the next_protocol and protocol fields from the metadata differs: next_protocol refers to the hash of the activated protocol. As a consequence, this block handled by protocol N and is the last block of that protocol.

val equal : protocol_info t -> protocol_info t -> bool

Equality on protocol levels maps.

val encoding : protocol_info t Tezos_base.TzPervasives.Data_encoding.t

Encoding for the protocol level's association map.
