pub trait Middleware<Element, Window>:
    Clone
    + PartialEq
    + Dyn
where
    Element: Clone + 'static,
    Window: Clone + 'static,
{
    // Required methods

    fn compute(
        &self,
        state: MiddlewareState<'_, Element, Window>,
    ) -> MiddlewareReturn;
}

Middleware used by compute_position.

Required Methods

fn name(&self) -> &'static str

The name of this middleware.

fn compute( &self, state: MiddlewareState<'_, Element, Window>, ) -> MiddlewareReturn

Executes this middleware.

Trait Implementations

impl<Element, Window> Clone for Box<dyn Middleware<Element, Window>>

where Element: Clone + 'static, Window: Clone + 'static,

fn clone(&self) -> Box<dyn Middleware<Element, Window>>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Element, Window> PartialEq<&Box<dyn Middleware<Element, Window>>> for Box<dyn Middleware<Element, Window>>

where Element: Clone + 'static, Window: Clone + 'static,

fn eq(&self, other: &&Box<dyn Middleware<Element, Window>>) -> 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<Element, Window> PartialEq for dyn Middleware<Element, Window>

where Element: Clone + 'static, Window: Clone + 'static,

fn eq(&self, other: &(dyn Middleware<Element, Window> + 'static)) -> 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.

Implementations on Foreign Types

impl<Element, Window, Factory> Middleware<Element, Window> for Instance<Factory, (Element, Window)>

where Element: Clone + 'static, Window: Clone + 'static, Factory: MiddlewareFactory<Element, Window>,
