Struct Restrict

pub struct Restrict<T>(/* private fields */);

Restricts a set of digits to a specific length.

Implementations

impl<T> Restrict<T>

pub const fn new(count: usize, collection: T) -> Self

Returns a new type that restricts collection to count digits.

Trait Implementations

impl<T: Clone> Clone for Restrict<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Restrict<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Restrict<T>

fn default() -> Restrict<T>

Returns the “default value” for a type.

impl<T> DigitCollection for Restrict<T>

where T: DigitCollection,

type Fallback = <T as DigitCollection>::Fallback

The digit collection that should be used after this collection’s range is exhausted.

fn has_zero_digit(&self) -> bool

Returns true if this collection has a symbol representing 0 at index 0.

fn zero_based(&self) -> bool

Returns true if this collection should start counting at 1 instead of 0. This function is only called if has_zero_digit() returns false.

fn len(&self) -> usize

Returns the number of digits in this collection.

fn digit(&self, index: usize) -> char

Returns the digit at location index.

fn fixed(&self) -> bool

If true, this digit collection can only produce a single digit.

fn is_empty(&self) -> bool

Returns true if this collection’s length is 0.

fn and<Other>(self, other: Other) -> Chain<Self, Other>

where Self: Sized, Other: DigitCollection,

Chains self and other into a single DigitCollection.

fn one_based(self) -> OneBased<Self>

where Self: Sized,

Returns this collection that indicates counting should start at 1 instead of 0.

impl<T: PartialEq> PartialEq for Restrict<T>

fn eq(&self, other: &Restrict<T>) -> 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.
