Struct MaybeIdxOne 

pub struct MaybeIdxOne<I: Index = usize> { /* private fields */ }

index equal to zero ro one, or a sentinel value

Trait Implementations

impl<I: Clone + Index> Clone for MaybeIdxOne<I>

fn clone(&self) -> MaybeIdxOne<I>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<I: Debug + Index> Debug for MaybeIdxOne<I>

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

Formats the value using the given formatter.

impl<I: Ord + Index> Ord for MaybeIdxOne<I>

fn cmp(&self, other: &MaybeIdxOne<I>) -> 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<I: PartialEq + Index> PartialEq for MaybeIdxOne<I>

fn eq(&self, other: &MaybeIdxOne<I>) -> 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<I: PartialOrd + Index> PartialOrd for MaybeIdxOne<I>

fn partial_cmp(&self, other: &MaybeIdxOne<I>) -> 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.

impl<I: Index> Unbind<<I as Index>::Signed> for MaybeIdxOne<I>

unsafe fn new_unbound(idx: I::Signed) -> Self

creates new value

fn unbound(self) -> I::Signed

returns the unbound value, unconstrained by safety invariants
