Struct structopt_flags::HostParam

pub struct HostParam {
    pub host_addr: IpAddr,
}

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

Trait Implementations

impl Clone for HostParam

fn clone(&self) -> HostParam

Returns a copy of the value.

default fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HostParam

fn fmt(&self, f: &mut Formatter) -> Result

impl StructOpt for HostParam

fn clap<'a, 'b>() -> App<'a, 'b>

Returns the corresponding clap::App.

fn from_clap(matches: &ArgMatches) -> Self

default fn from_args() -> Self

Gets the struct from the command line arguments. Print the error message and quit the program in case of failure.

default fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.
