Methods

impl<'a> Args<'a>

fn new(text: &'a str) -> Args

provide a usage string from which we extract flag definitions

fn quit(&self, msg: &str) -> !

bail out of program with non-zero return code. May force this to panic instead with the EASY_DONT_QUIT_PANIC environment variable.

fn declarations(&mut self, struct_name: &str) -> String

create suggested variable or struct declarations for accessing the flags...

fn dump(&mut self)

fn get_string(&self, name: &str) -> String

get flag as a string, quitting otherwise.

fn get_integer(&self, name: &str) -> i32

get flag as an integer, quitting otherwise.

fn get_float(&self, name: &str) -> f32

get flag as a float, quitting otherwise.

fn get_bool(&self, name: &str) -> bool

get flag as a bool, quitting otherwise.

fn get_infile(&self, name: &str) -> Box<Read>

get multiple flag as an array of strings, quitting otherwise.

fn get_integers(&self, name: &str) -> Vec<i32>

get multiple flag as an array of integers, quitting otherwise.

fn get_floats(&self, name: &str) -> Vec<f32>
