Conversions between units of measure that are based on bytes (like kilobytes, megabytes, gigabytes, and words).

t's are created with create measure value, as in Byte_units.create `Megabytes 100.

module Measure : sig ... end
type t
include sig ... end
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (Base.Int.t -> t) Bin_prot.Read.reader
val bin_reader_t : t Bin_prot.Type_class.reader
val bin_size_t : t Bin_prot.Size.sizer
val bin_write_t : t Bin_prot.Write.writer

val t_of_sexp : Sexplib.Sexp.t -> t
val sexp_of_t : t -> Sexplib.Sexp.t
val create : Measure.t -> Base.Float.t -> t

create measure value creates a t from value units of the given measure.

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool

val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

include Base.Stringable.S with type t := t
val of_string : string -> t
val to_string : t -> string
val to_string_hum : ?measure:Measure.t -> t -> Base.String.t

to_string_hum ?measure t returns a string representation of t. If measure is not given then the largest measure (excluding `Words) is used that causes the translated value to exceed 1.

For example Byte_units.to_string_hum (Byte_units.create `Bytes 1000.) gives 1000b, but Byte_units.to_string_hum (Byte_units.create `Bytes 1500.) gives 1.46484k.

val bytes : t -> Base.Float.t

val megabytes : t -> Base.Float.t
val gigabytes : t -> Base.Float.t
val words : t -> Base.Float.t
val scale : t -> Base.Float.t -> t

scale t mul scale the measure t by mul
