#[repr(C)]
pub struct Key<T: 'static + Sized> { /* private fields */ }

Implementations

impl<T: 'static + Sized> Key<T>

pub fn as_u64(&self) -> u64

pub fn as_u64_xor_type(&self) -> u64

a weak pseudo hash of the key. Used to check for equality

Trait Implementations

impl<T: 'static + Sized> Clone for Key<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: 'static + Sized> Debug for Key<T>

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

Formats the value using the given formatter.

impl<T: 'static + Sized> Default for Key<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: 'static + Sized> Display for Key<T>

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

Formats the value using the given formatter.

impl<T: 'static + Sized> From<KeyData> for Key<T>

fn from(value: KeyData) -> Self

Converts to this type from the input type.

impl<T: 'static + Sized> From<OwnedKey<T>> for Key<T>

fn from(value: OwnedKey<T>) -> Self

Converts to this type from the input type.

impl<T: 'static + Sized> Hash for Key<T>

fn hash<H: Hasher>(&self, state: &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: 'static + Sized> Index<Key<T>> for Arenas

type Output = T

The returned type after indexing.

fn index(&self, key: Key<T>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T: 'static + Sized> Key for Key<T>

fn data(&self) -> KeyData

Gets the KeyData stored in this key.

fn null() -> Self

Creates a new key that is always invalid and distinct from any non-null key. A null key can only be created through this method (or default initialization of keys made with new_key_type!, which calls this method).

fn is_null(&self) -> bool

Checks if a key is null. There is only a single null key, that is a.is_null() && b.is_null() implies a == b.

impl<T: 'static + Sized> Ord for Key<T>

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<T: 'static + Sized> PartialEq for Key<T>

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<T: 'static + Sized> PartialOrd for Key<T>

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.
