[−][src]Function display_utils::unicode_block_bar
pub fn unicode_block_bar(max_length: usize, proportion: f32) -> impl Display
Print a loading-style bar using Unicode block characters.
The bar is very high-resolution: 8 states can be represented per character.
Accepts the total length of the bar and a float from 0.0 to 1.0 as the filled proportion.
Prints exactly max_length chars (not bytes!), right-padded with spaces.
