Class type

Defines a Michelson expression representation as a Micheline node with canonical (int) location and Michelson_v1_primitives.prim as content.

Types expr and node both define representation of Michelson expressions and are indeed the same type internally, although this is not visible outside Micheline due to interface abstraction.

Locations are used by Micheline mostly for error-reporting and pretty- printing expressions. canonical_location is simply an int.

Annotations attached to Michelson expressions.

Represents a Michelson expression as canonical Micheline.

A record containing either an underlying serialized representation of an expression or a deserialized one, or both. If either is absent, it will be computed on-demand.

Same as expr, but used in different contexts, as required by Micheline's abstract interface.

val lazy_expr : expr -> lazy_expr
type t = {
  1. code : lazy_expr;
  2. storage : lazy_expr;
}

Type t joins the contract's code and storage in a single record.

val deserialization_cost_estimated_from_bytes : int -> Gas_limit_repr.cost
val deserialized_cost : expr -> Gas_limit_repr.cost
val bytes_node_cost : bytes -> Gas_limit_repr.cost
val force_decode_cost : lazy_expr -> Gas_limit_repr.cost

Returns (a lower bound on) the cost to deserialize a lazy_expr. If the expression has already been deserialized (i.e. the lazy expression contains the deserialized value or both the bytes representation and the deserialized value) then the cost is free.

val stable_force_decode_cost : lazy_expr -> Gas_limit_repr.cost

Like force_decode_cost, excepted that the returned cost does not depend on the internal state of the lazy_expr. This means that the cost is never free (excepted for zero bytes expressions).

val force_bytes_cost : lazy_expr -> Gas_limit_repr.cost

Returns the cost to serialize a lazy_expr. If the expression has already been deserialized (i.e. le lazy expression contains the bytes representation or both the bytes representation and the deserialized value) then the cost is free.

val unit : expr
val unit_parameter : lazy_expr
val is_unit : expr -> bool
val is_unit_parameter : lazy_expr -> bool
val strip_annotations : node -> node
val strip_locations_cost : _ michelson_node -> Gas_limit_repr.cost
val strip_annotations_cost : node -> Gas_limit_repr.cost
val micheline_serialization_cost : expr -> Gas_limit_repr.cost

Computes the cost of serializing a given term.

module Micheline_size : sig ... end
val micheline_nodes : node -> int

micheline_nodes root returns the number of internal nodes in the micheline expression held from root.

val fold : ('loc, 'prim) Tezos_protocol_environment_alpha.Micheline.node -> 'acc -> ('acc -> ('loc, 'prim) Tezos_protocol_environment_alpha.Micheline.node -> 'acc) -> 'acc

fold node i f traverses node applying f on an accumulator initialized by i.
