[−][src]Struct structopt_flags::HostParam
This struct provides the --host
and -H
cli option to get ageneric IP 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::{IpAddr,Ipv6Addr}; use structopt::StructOpt; #[derive(Debug, StructOpt)] #[structopt(name = "ip_param", about = "An example using the HostParam option")] struct Opt { #[structopt(flatten)] host_ip: structopt_flags::HostParam, } fn main() { let opt = Opt::from_args(); let ip = opt.host_ip.host_addr; }
Fields
host_addr: IpAddr
Set the host IP (both IpV4 and IpV6 are supported)
