package macaddr
A library for manipulation of MAC address representations.
v5.3.0 - homepage
Parse_error (err,packet) is raised when parsing of the MAC address syntax fails. err contains a human-readable error and packet is the original octet list that failed to parse.
Functions converting MAC addresses to/from octets/string
val of_octets_exn : string -> tof_octets_exn buf is the hardware address extracted from buf. Raises Parse_error if buf has not length 6.
val of_octets : string -> (t, [> `Msg of string ]) Stdlib.resultSame as of_octets_exn but returns a result type instead of raising an exception.
val of_string_exn : string -> tof_string_exn mac_string is the human-readable hardware address represented by mac_string. Raises Parse_error if mac_string is not a valid representation of a MAC address.
val of_string : string -> (t, [> `Msg of string ]) Stdlib.resultSame as of_string_exn but returns a result type instead of raising an exception.
val to_octets : t -> stringto_octets mac_addr is a string of size 6 encoding mac_addr as a sequence of bytes.
val to_string : ?sep:char -> t -> stringto_string ?(sep=':') mac_addr is the sep-separated string representation of mac_addr, i.e. xx:xx:xx:xx:xx:xx.
val pp : Stdlib.Format.formatter -> t -> unitpp f mac_addr outputs a human-readable representation of mac_addr to the formatter f.
val broadcast : tbroadcast is ff:ff:ff:ff:ff:ff.
val make_local : (int -> int) -> tmake_local bytegen creates a unicast, locally administered MAC address given a function mapping octet offset to octet value.
val get_oui : t -> intget_oui macaddr is the integer organization identifier for macaddr.
val is_local : t -> boolis_local macaddr is the predicate on the locally administered bit of macaddr.
val is_unicast : t -> boolis_unicast macaddr the is the predicate on the unicast bit of macaddr.
