module Signedness : sig ... end

val empty : t

val create : Base.int -> t

create n create a n bit constant, initialized to hold all 0s.

val width : t -> Base.int

Bit width of constant

val to_binary_string : t -> Base.string

Convert a constant to a string of '1' and '0' chars.

val to_binary_string_hum : t -> Base.string

Same as to_binary_string but adds '_'s every chars

val to_int : t -> Base.int

Convert constant to an int. Bits above Int.num_bits are dropped.

val to_int32 : t -> Base.int32

Convert constant to an int32. Bits above Int32.num_bits are dropped.

val to_int64 : t -> Base.int64

Convert constant to an int64. Bits above Int64.num_bits are dropped.

val to_int64_array : t -> Base.int64 Base.array

Convert to array of int64s

val to_z : signedness:Signedness.t -> t -> Hardcaml__.Zarith.Z.t

Convert to an arbitrary precision integer.

val to_hex_string : signedness:Signedness.t -> t -> Base.string

Convert to a hex encoded string.

val of_binary_string : Base.string -> t

Convert a string containing '1' and '0' characters to a constant. Width is inferred from the strings length.

val of_binary_string_hum : Base.string -> t

Same as of_binary_string but allow '_' chars

val of_int : width:Base.int -> Base.int -> t

Create a constant from the given int value.

val of_int32 : width:Base.int -> Base.int32 -> t

Create a constant from the given int32 value

val of_int64 : width:Base.int -> Base.int64 -> t

Create a constant from the given int64 value

val of_int64_array : width:Base.int -> Base.int64 Base.array -> t

Create from an array of int64s

val of_z : width:Base.int -> Hardcaml__.Zarith.Z.t -> t

Convert from an arbitrary precision integer.

val of_hex_string : 
  signedness:Signedness.t ->
  width:Base.int ->
  Base.string ->
  t

Create from a hex encoded string.

val of_octal_string : 
  signedness:Signedness.t ->
  width:Base.int ->
  Base.string ->
  t

Create from an octal encoded string.

val int_of_hex_char : Base.char -> Base.int

Utility conversion functions to/from hex chars

val hex_char_of_int : Base.int -> Base.char

module type Bit = sig ... end

module Make_bit_list (Bit : Bit) : sig ... end

Create constant conversion functions from lists of some inner Bit.t type.

val of_bit_list : Base.int Base.list -> t

val to_bit_list : t -> Base.int Base.list

val pp : Base.Formatter.t -> t -> Base.unit

module Raw : sig ... end

Convert to from constants from raw bit patterns stored in strings and bytes. Data is copied and resized as appropriate.
