Struct Chain

pub struct Chain<A, B> { /* private fields */ }

A combination of two DigitCollection implementations.

Digits from A will be selected before digits from B.

Implementations

impl<A, B> Chain<A, B>

pub const fn new(a: A, b: B) -> Self

Returns a new combined set of digits.

Trait Implementations

impl<A: Clone, B: Clone> Clone for Chain<A, B>

fn clone(&self) -> Chain<A, B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Debug, B: Debug> Debug for Chain<A, B>

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

Formats the value using the given formatter.

impl<A: Default, B: Default> Default for Chain<A, B>

fn default() -> Chain<A, B>

Returns the “default value” for a type.

impl<A, B> DigitCollection for Chain<A, B>

where A: DigitCollection, B: DigitCollection,

type Fallback = Chain<<A as DigitCollection>::Fallback, <B 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<A: PartialEq, B: PartialEq> PartialEq for Chain<A, B>

fn eq(&self, other: &Chain<A, B>) -> 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.
