Trait Implementations

impl<Element: Clone, Window: Clone, T: Clone> Clone for Derivable<'_, Element, Window, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, Element: Clone, Window: Clone, T: Clone> From<&'a dyn Fn(MiddlewareState<'_, Element, Window>) -> T> for Derivable<'a, Element, Window, T>

fn from(value: DerivableFn<'a, Element, Window, T>) -> Self

Converts to this type from the input type.

impl<Element: Clone, Window: Clone, T: Clone> From<T> for Derivable<'_, Element, Window, T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<Element: Clone, Window: Clone, T: Clone + PartialEq> PartialEq for Derivable<'_, Element, Window, 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.
