[−][src]Struct structopt_flags::HostV4Param
This struct provides the --host
and -H
cli option to get an IPv4 address
No default is provided and the parameter is mandatory This option is not global
extern crate structopt_flags; #[macro_use] extern crate structopt; use std::net::Ipv4Addr; use structopt::StructOpt; #[derive(Debug, StructOpt)] #[structopt(name = "ipv4_param", about = "An example using the HostV4Param option")] struct Opt { #[structopt(flatten)] host_ip: structopt_flags::HostV4Param, } fn main() { let opt = Opt::from_args(); let ipv4 = opt.host_ip.host_addr; }
Fields
host_addr: Ipv4Addr
Set the host IP (Ipv4 only)
