Ipv4 address conversions
val of_cstruct : Cstruct.t -> (Ipaddr.V4.t, [> `Msg of string ]) Stdlib.result
of_cstruct c
parses the first 4 octets of c
into an IPv4 address.
val of_cstruct_exn : Cstruct.t -> Ipaddr.V4.t
of_cstruct_exn
parses the first 4 octets of c
into an IPv4 address. Raises Ipaddr.Parse_failure
on error.
val to_cstruct : ?allocator:(int -> Cstruct.t) -> Ipaddr.V4.t -> Cstruct.t
to_cstruct ipv4
is a cstruct of length 4 encoding ipv4
. The cstruct is allocated using allocator
. If allocator
is not provided, Cstruct.create
is used.
val write_cstruct_exn : Ipaddr.V4.t -> Cstruct.t -> unit
write_cstruct_exn ipv4 cs
writes 4 bytes into cs
representing the ipv4
address octets. Raises Ipaddr.Parse_error
if cs
is not at least 4 bytes long.
