Index(usize)

Auto-generated index key

Implementations

impl WidgetKey

pub fn string(s: impl Into<String>) -> Self

Create a string key.

pub const fn index(i: usize) -> Self

Create an index key.

Trait Implementations

impl Clone for WidgetKey

fn clone(&self) -> WidgetKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetKey

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

Formats the value using the given formatter.

impl Hash for WidgetKey

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 WidgetKey

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