Struct Arrow

pub struct Arrow<'a, Element: Clone + 'static, Window: Clone> { /* private fields */ }

Arrow middleware.

Provides data to position an inner element of the floating element so that it appears centered to the reference element.

See the Rust Floating UI book for more documentation.

Implementations

impl<'a, Element: Clone + 'static, Window: Clone> Arrow<'a, Element, Window>

pub fn new(options: ArrowOptions<Element>) -> Self

Constructs a new instance of this middleware.

pub fn new_derivable( options: Derivable<'a, Element, Window, ArrowOptions<Element>>, ) -> Self

Constructs a new instance of this middleware with derivable options.

pub fn new_derivable_fn( options: DerivableFn<'a, Element, Window, ArrowOptions<Element>>, ) -> Self

Constructs a new instance of this middleware with derivable options function.

Trait Implementations

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

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

The name of this middleware.

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

Executes this middleware.

impl<Element: Clone, Window: Clone> MiddlewareWithOptions<Element, Window, ArrowOptions<Element>> for Arrow<'_, Element, Window>

fn options(&self) -> &Derivable<'_, Element, Window, ArrowOptions<Element>>

The options passed to this middleware.

impl<'a, Element: PartialEq + Clone + 'static, Window: PartialEq + Clone> PartialEq for Arrow<'a, Element, Window>

fn eq(&self, other: &Arrow<'a, 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.
