type t

The shell's notion of a level: an integer indicating the number of blocks since genesis: genesis is 0, all other blocks have increasing levels from there.

type raw_level = t

module Set : Tezos_protocol_environment_alpha.Set.S with type elt = t

module Map : Tezos_protocol_environment_alpha.Map.S with type key = t

val encoding : raw_level Tezos_protocol_environment_alpha.Data_encoding.t

raises Invalid_argument
when the level to encode is not positive

val rpc_arg : raw_level Tezos_protocol_environment_alpha.RPC_arg.arg

val pp : Tezos_protocol_environment_alpha.Format.formatter -> raw_level -> unit

include Tezos_protocol_environment_alpha.Compare.S with type t := raw_level

  raw_level ->
  Tezos_protocol_environment_alpha.Bounded.Non_negative_int32.t

val of_int32_exn : int32 -> raw_level

raises Invalid_argument
when the level to encode is negative

val of_int32 : 
  int32 ->
  raw_level Tezos_protocol_environment_alpha.Error_monad.tzresult

Can trigger Unexpected_level error when the level to encode is negative

val root : raw_level

val succ : raw_level -> raw_level

val pred : raw_level -> raw_level option

val pred_dontreturnzero : raw_level -> raw_level option

Return the predecessor of l when l >= 2, otherwise return None.

val add : raw_level -> int -> raw_level

add l i i must be positive

val sub : raw_level -> int -> raw_level option

sub l i i must be positive
