Struct Arrow

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

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.
