pub fn style( self, style: impl Fn(&Theme) -> Style + 'a, ) -> ProgressBar<'a, Theme>

where <Theme as Catalog>::Class<'a>: From<Box<dyn Fn(&Theme) -> Style + 'a>>,

Sets the style of the ProgressBar.

pub fn class( self, class: impl Into<<Theme as Catalog>::Class<'a>>, ) -> ProgressBar<'a, Theme>

Sets the style class of the ProgressBar.
