Struct Instance 

pub struct Instance<T>
where
    T: Tabulate,
{ /* private fields */ }

A zero-sized guard that tracks the lifetime of an instance of T.

Constructing an Instance<T> increments the population count of T. Dropping an Instance<T> decrements the population count of T.

Implementations

impl<T> Instance<T>

where T: Tabulate,

pub fn new() -> Self

Constructs a new Instance<T>, representing the extant lifetime of an instance of T.

Trait Implementations

impl<T> Clone for Instance<T>

where T: Tabulate,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Instance<T>

where T: Tabulate,

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

Formats the value using the given formatter.

impl<T> Default for Instance<T>

where T: Tabulate,

fn default() -> Self

Returns the “default value” for a type.

impl<T> Drop for Instance<T>

where T: Tabulate,

fn drop(&mut self)

Executes the destructor for this type.

impl<T> Hash for Instance<T>

where T: Tabulate,

fn hash<H: Hasher>(&self, _: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> Ord for Instance<T>

where T: Tabulate,

fn cmp(&self, _: &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<T> PartialEq for Instance<T>

where T: Tabulate,

fn eq(&self, _: &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<T> PartialOrd for Instance<T>

where T: Tabulate,

fn partial_cmp(&self, _: &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.

impl<T> Eq for Instance<T>

where T: Tabulate,
