Module Ipaddr_cstruct.V4

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.
