Trait Implementations

impl Clone for HostOpt

fn clone(&self) -> HostOpt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HostOpt

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

impl GetWithDefault for HostOpt

type Item = IpAddr

fn get_with_default<T: Into<Self::Item>>(&self, default: T) -> Self::Item

This function can be used to retrieve the value of the command line option taking in account the default value used as argument

impl StructOpt for HostOpt

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

Returns the corresponding clap::App.

fn from_clap(matches: &ArgMatches) -> Self

Creates the struct from clap::ArgMatches. It cannot fail with a parameter generated by clap by construction.

fn from_args() -> Self

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

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.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> 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.

impl StructOptInternal for HostOpt
