Struct OptRef 

pub struct OptRef<'a, C> {
    pub delta: OptDelta,
    pub value: &'a OptValue<C>,
}

A low-cost copyable Opt that stores a reference to the value

Fields

delta: OptDelta

value: &'a OptValue<C>

Trait Implementations

impl<'a, C: Clone> Clone for OptRef<'a, C>

fn clone(&self) -> OptRef<'a, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, C: Debug> Debug for OptRef<'a, C>

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

Formats the value using the given formatter.

impl<'a, V> From<&'a Opt<V>> for OptRef<'a, V>

fn from(o: &'a Opt<V>) -> Self

Converts to this type from the input type.

impl<'a, C: Array<Item = u8>> Len for OptRef<'a, C>

const CAPACITY: Option<usize> = None

The maximum number of elements that this data structure can acommodate.

fn len(&self) -> usize

Get the runtime size (in bytes) of a struct

fn is_full(&self) -> bool

Is there no room left in this collection?

fn is_empty(&self) -> bool

Check if the runtime size is zero

impl<'a, C> Ord for OptRef<'a, C>

where C: Array<Item = u8>,

fn cmp(&self, other: &Self) -> 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<'a, C> PartialEq for OptRef<'a, C>

where C: Array<Item = u8>,

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<'a, C> PartialOrd for OptRef<'a, C>

where C: Array<Item = u8>,

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.
