Struct BreadthFirstManager 

pub struct BreadthFirstManager<'item, Tail: BreadthFirst<'item>> { /* private fields */ }

Helper struct for a breadth-first zip: a counter controlling the maximum index sum of the internal recursive implementation.

Implementations

impl<'item, Tail: BreadthFirst<'item>> BreadthFirstManager<'item, Tail>

pub const fn new(tail: Tail) -> Self

Initialize a new breadth-first algorithm.

pub fn next(&'item self) -> Option<<Tail::Advance as Flatten>::Flattened>

Like Iterator::next but with a generic lifetime. Why not implement Iterator? https://stackoverflow.com/questions/68606470/how-to-return-a-reference-when-implementing-an-iterator

Trait Implementations

impl<'item, Tail: Clone + BreadthFirst<'item>> Clone for BreadthFirstManager<'item, Tail>

fn clone(&self) -> BreadthFirstManager<'item, Tail>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'item, Tail: Debug + BreadthFirst<'item>> Debug for BreadthFirstManager<'item, Tail>

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

Formats the value using the given formatter.

impl<'item, Tail: Default + BreadthFirst<'item>> Default for BreadthFirstManager<'item, Tail>

fn default() -> BreadthFirstManager<'item, Tail>

Returns the “default value” for a type.

impl<'item, Tail: Ord + BreadthFirst<'item>> Ord for BreadthFirstManager<'item, Tail>

fn cmp(&self, other: &BreadthFirstManager<'item, Tail>) -> 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<'item, Tail: PartialEq + BreadthFirst<'item>> PartialEq for BreadthFirstManager<'item, Tail>

fn eq(&self, other: &BreadthFirstManager<'item, Tail>) -> 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<'item, Tail: PartialOrd + BreadthFirst<'item>> PartialOrd for BreadthFirstManager<'item, Tail>

fn partial_cmp( &self, other: &BreadthFirstManager<'item, Tail>, ) -> 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.
