Struct DeleteOnDropWrapper

Source 
pub struct DeleteOnDropWrapper<M> {
    inner: M,
}
Available on crate feature metrics only.
Expand description

A wrapper for metrics to require delete on drop semantics

The wrapper behaves like regular metrics but only provides functions to create delete-on-drop variants. This way, no metrics of this type can be leaked.

In situations where the delete-on-drop behavior is not desired or in legacy code, use the raw variants of the metrics, as defined in self::raw.

fn fg(&self, value: Color) -> Painted<&T>

use yansi::{Paint, Color};

painted.fg(Color::White);

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>

Enables the yansi Quirk value.
