Expand description

Enum representing text attributes, largely for text formatting.

Text attributes are typically applied to a Style, Color, or Painted struct via the corresponding chainable builder methods such as bold() or italic(). The returned value will apply the attribute(s) when rendered or printed.

Attributes are idempotent, so applying an attribute more than once has no more affect than applying it once.

Terminal Support

Whether an applied attribute actually has an effect on how text is rendered in a terminal depends on the terminal’s support for the attribute as well as the terminal’s configuration. Common attributes, such as bold, dim, italic, underline, and strike typically have good support and are largely reliable. Less commonly supported attributes like conceal and invert will usually be supported by “modern” terminals. Rarely supprted attributes, like blink and rapid blink will usually have no effect when applied.

Example

use yansi::{Style, Color::Red};

/// A style with red foreground and every "common" attribute applied.
static MAD: Style = Red.bold().dim().italic().underline().strike();
