Struct getopt::prelude::Opt

pub struct Opt(pub Option<char>, pub Option<String>);

A single option.

For Opt(x, y):

• x is Some character, or None if no option was found.
• y is Some string, or None if no argument was expected.

Example

use getopt::prelude::*;

// args = ["program", "-abc", "foo"];
let optstring = "ab:c";
let mut state = State::new();

assert_eq!(Opt(Some('a'), None), getopt(&args, optstring, &mut state)?);
assert_eq!(
    Opt(Some('b'), Some("c".to_string())),
    getopt(&args, optstring, &mut state)?
);
assert_eq!(Opt(None, None), getopt(&args, optstring, &mut state)?);

Trait Implementations

impl PartialEq<Opt> for Opt

fn eq(&self, other: &Opt) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Opt) -> bool

This method tests for !=.

impl Ord for Opt

fn cmp(&self, other: &Opt) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl Eq for Opt

impl PartialOrd<Opt> for Opt

fn partial_cmp(&self, other: &Opt) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Opt) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Opt) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Opt) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Opt) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Debug for Opt

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

Formats the value using the given formatter.
