Trait ThemeFn 

pub trait ThemeFn<State, Theme> {
    // Required method
    fn theme(&self, state: &State) -> Option<Theme>;
}

The theme logic of some Application.

Any implementors of this trait can be provided as an argument to Application::theme.

iced provides two implementors:

• the built-in Theme itself
• and any Fn(&State) -> impl Into<Option<Theme>>.

Required Methods

fn theme(&self, state: &State) -> Option<Theme>

Returns the theme of the Application for the current state.

If None is returned, iced will try to use a theme that matches the system color scheme.

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