Struct Key

pub struct Key(/* private fields */);

Key is a dynamically typed wrapper around any type that implements `Any + Eq

• Hash(note thatAnyimplies’static). Key acts as a transparent wrapper for these traits, where EqandPartialEq` in particular perform dynamic type checks before determining value equality.

Implementations

impl Key

pub fn new<T>(value: T) -> Key

where T: Keyable + 'static,

This function returns a new key with the given value. The prescribed trait bound on machinery::Keyable refers to a hidden trait that is automatically implemented for types that implement Any + Eq + Hash. This trait is hidden because it should not be implemented manually.

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Key

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

Formats the value using the given formatter.

impl<T> From<Rc<T>> for Key

where T: Keyable + 'static,

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

Converts to this type from the input type.

impl Hash for Key

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

where H: Hasher,

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 PartialEq for Key

fn eq(&self, other: &Key) -> 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.
