Expand description

A trait for rendering a column in a progress bar.

Required Methods§

Source

fn render(&self, task: &Task) -> Vec<Span>

Render the column for the given task.

Provided Methods§

Source

fn render_with_width( &self, task: &Task, _available_width: Option<usize>, ) -> Vec<Span>

Render the column with an available width hint.

Columns that can expand (like BarColumn with expand: true) should override this to use the provided width. Default implementation ignores the width and calls render().
