Tezos_lazy_containers.Lazy_vectorA lazy vector is a fixed-size key-value association where each value is created dynamically.
In many ways this data structure mimics an array, but its lookup has logarithmic time complexity and it supports non-int keys.
module type KeyS = sig ... endKeyS is the qualifier signature for key types in the lazy vector. Externally visible and accessible keys of the lazy vector are always non-negative. However, the lazy vector implementation may internally use negative keys therefore modules of type KeyS must support them.
module type S = sig ... endmodule Int32Vector : S with type key = int32module Int64Vector : S with type key = int64module Mutable : sig ... endMake generates a lazy vector module using a given Key module.
