rustc/vendor/tabled-0.15.0/examples/format.rs

//! This example demonstrates using the [`Format`] [`CellOption`] factory to alter
//! the cells of a [`Table`].
//!
//! * Note how [`Format::content()`] gives access to the respective cell content for replacement.
//! And [`Format::positioned()`] additionally provides the index coordinates of that cell.
//!
//! * Note how the [std] [`format!`] macro is used to update the values of the affected cells.
