Struct RawKey 

#[repr(transparent)]
pub struct RawKey(u64);

The key used in IdTypeMap, which is a combination of an Id and a TypeId.

This key can be used to remove or access values in the IdTypeMap without knowledge of the TypeId T that is required for other accessors.

RawKeys make no guarantees about layout or their ability to be persisted. They only produce deterministic results if they are used with the map they were initially obtained from. Using them on other instances of IdTypeMap may produce unexpected behavior.

Implementations

impl RawKey

pub fn new<T: 'static>(id: Id) -> Self

Create a new key for the given type.

Note that two keys with the same id but different types will be different keys.

use egui::{Id, util::id_type_map::RawKey};
assert_ne!(
    RawKey::new::<i32>(Id::NULL),
    RawKey::new::<String>(Id::NULL),
);

Trait Implementations

impl Clone for RawKey

fn clone(&self) -> RawKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RawKey

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

Formats the value using the given formatter.

impl Hash for RawKey

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 PartialEq for RawKey

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