Trait Middleware 

pub trait Middleware<Element: Clone + 'static, Window: Clone + 'static>:
    Clone
    + PartialEq
    + Dyn {
    // Required methods
    fn name(&self) -> &'static str;
    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: Clone + 'static, Window: Clone + 'static> Clone for Box<dyn Middleware<Element, Window>>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Element: Clone + 'static, Window: Clone + 'static> PartialEq for dyn Middleware<Element, Window>

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.

impl<Element: Clone + 'static, Window: Clone + 'static> PartialEq<&Box<dyn Middleware<Element, Window>>> for Box<dyn Middleware<Element, Window>>

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
