Struct Count 

pub struct Count {
    pub count: u32,
}

A switch parameter that counts the number of times it appears on the command line. Enables things like increasing verbosity levels via -v, -vv, -vvv

Fields

count: u32

The number of times this switch appeared

Trait Implementations

impl Clone for Count

fn clone(&self) -> Count

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Count

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

Formats the value using the given formatter.

impl Default for Count

fn default() -> Count

Returns the “default value” for a type.

impl Hash for Count

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 Ord for Count

fn cmp(&self, other: &Count) -> 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<'arg> Parameter<'arg> for Count

fn absent() -> Result<Self, RequiredError>

This parameter was absent from the command line.

fn present<E: Error<'arg>>(_arg: impl ArgAccess<'arg>) -> Result<Self, E>

This parameter appeared on the command line.

fn add_present<E: Error<'arg>>( &mut self, _arg: impl ArgAccess<'arg>, ) -> Result<(), E>

This parameter appeared more than once on the command line.

fn arg<E: Error<'arg>>(argument: &'arg Arg) -> Result<Self, E>

This parameter got an argument from the command line.

fn add_arg<E: Error<'arg>>(&mut self, argument: &'arg Arg) -> Result<(), E>

This parameter appeared an additional time on the command line, with an argument.

impl ParameterUsage for Count

const VALUE: ParameterValueKind = help::ParameterValueKind::Flag

The nature of the value this takes as an argument, if any.

const REQUIREMENT: Requirement = help::Requirement::Optional

Whether or not this parameter must appear at least once.

const REPETITION: Repetition = help::Repetition::Multiple

Whether or not this parameter may appear more than once.

impl PartialEq for Count

fn eq(&self, other: &Count) -> 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 PartialOrd for Count

fn partial_cmp(&self, other: &Count) -> 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.
