Enum SimpleOpt 

pub enum SimpleOpt<'a> {
    Basic(&'a str),
    Stdin,
    Flag(&'a str),
    Pair(&'a str, &'a str),
    Done,
    Other(&'a Opt),
}

Alternative labeling of Opt which is easier to use in match statements.

For each variant below, we describe which Opt variant that it is derived from.

Examples

Here we use Opt::simplify to perform the borrowing:

let x = Long("verbose".to_string());

match x.simplify() {
  Flag("v" | "verbose") => println!("Verbose option captured!"),
  _ => panic!(),
}

Variants

Basic(&'a str)

NonOption

Stdin

Dash

Flag(&'a str)

Short or Long

Pair(&'a str, &'a str)

ShortPair or LongPair

Done

Terminator

Other(&'a Opt)

All other Opt variants not covered

Trait Implementations

impl<'a> Clone for SimpleOpt<'a>

fn clone(&self) -> SimpleOpt<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SimpleOpt<'a>

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

Formats the value using the given formatter.

impl<'a> Display for SimpleOpt<'a>

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

Formats the value using the given formatter.

impl<'a> From<SimpleOpt<'a>> for Opt

fn from(value: SimpleOpt<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for SimpleOpt<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for SimpleOpt<'a>

fn cmp(&self, other: &SimpleOpt<'a>) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for SimpleOpt<'a>

fn eq(&self, other: &SimpleOpt<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for SimpleOpt<'a>

fn partial_cmp(&self, other: &SimpleOpt<'a>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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