Expand description

A trait used to add formatting attributes to displayable items.

If using the concolor feature, this trait assumes that the items are going to be printed to stderr. If you are printing to stdout, use the StdoutFmt trait instead.

Attributes specified through this trait are not composable (i.e: the behaviour of two nested attributes each with a conflicting attribute is left unspecified).

Provided Methods§

source

fn fg<C: Into<Option<Color>>>(self, color: C) -> Foreground<Self>where Self: Display,

Give this value the specified foreground colour.
