Struct app::Opt

pub struct Opt<'app> { /* fields omitted */ }

Option

Methods

impl<'app> Opt<'app>

fn new<'s: 'app, V>(name: &'app str, value: V) -> Self where
    V: OptValueParse<'app>, 

name and value, App will maintain the value(&mut T).

for example,

• follows's charset is Opt's Name

• h, v and cs is Opt's short

• help, version and charset is Opt's long

• help is Opt's help message

--charset charset,-cs charset         sets the charset Zipcs using
--help,-h                             show the help message
--version,-v                          show the version message

fn sort_key(self, sort_key: &'app str) -> Self

Default is Opt's name

fn optional(self) -> Self

set Opts optional as true(default is false)(override OptValueParse's default and check).

App will will not check it's value if the Opt not occurs and create help message without default's value if it is true.

fn short(self, short: char) -> Self

short

fn long(self, long: &'app str) -> Self

long

fn help(self, help: &'app str) -> Self

help message

fn name_get(&self) -> &'app str

fn sort_key_get(&self) -> &'app str

fn short_get(&self) -> Option<String>

fn long_get(&self) -> Option<String>

fn help_get(&self) -> &str

fn typo_get(&self) -> &OptTypo

fn count_get(&self) -> &usize
