Enum LimitValue

pub enum LimitValue<T> {
    Limit(T),
    Limitless,
}

A structure that represents a limit value.

Variants

Limit(T)

finite limit value

Limitless

infinite limit value

Implementations

impl<T> LimitValue<T>

pub fn is_limit(&self) -> bool

Verify if this limit is finite.

pub fn is_limitless(&self) -> bool

Verify if this limit is infinite.

pub fn as_value(&self) -> Result<&T, Error>

Get the limit value.

pub fn as_value_or<'a, TF>(&'a self, default: TF) -> &T

where TF: Fn() -> &'a T,

Get the limit value.

Trait Implementations

impl<T: Clone> Clone for LimitValue<T>

fn clone(&self) -> LimitValue<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for LimitValue<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for LimitValue<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Display> Display for LimitValue<T>

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

Formats the value using the given formatter.

impl<T> From<Option<T>> for LimitValue<T>

fn from(value: Option<T>) -> Self

Converts to this type from the input type.

impl<T: ToString> Hash for LimitValue<T>

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<T: Ord> Ord for LimitValue<T>

fn cmp(&self, other: &LimitValue<T>) -> 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<T: PartialEq> PartialEq for LimitValue<T>

fn eq(&self, other: &Self) -> 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<T: PartialOrd> PartialOrd for LimitValue<T>

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