Any widgets supporting Classes must implement this trait

Required Methods

fn classes(&self) -> &Classes

fn classes_mut(&mut self) -> &mut Classes

Provided Methods

fn with_class(self, class: impl Into<ClassName>) -> Self

where Self: Sized,

Add the given class by consuming self

fn with_class_if(self, class: impl Into<ClassName>, condition: bool) -> Self

where Self: Sized,

Add the given class by consuming self if the condition is true

fn add_class(&mut self, class: impl Into<ClassName>) -> &mut Self

where Self: Sized,

Add the given class in-place

fn add_class_if( &mut self, class: impl Into<ClassName>, condition: bool, ) -> &mut Self

where Self: Sized,

Add the given class in-place if the condition is true

fn has(&self, class: impl Into<ClassName>) -> bool

True if the class is present

Dyn Compatibility

This trait is not dyn compatible.

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