Struct Style 

pub struct Style { /* private fields */ }

Whether styled output is wanted, and the sequences for it.

Construct with Style::for_stderr at the point of use rather than caching one: the decision is cheap, and a cached one taken before a stream was redirected would be wrong.

Implementations

impl Style

pub fn for_stderr() -> Self

The style for diagnostics: colour only when stderr is a terminal.

pub fn for_stdout() -> Self

The style for help text, which is printed to stdout when it was asked for and to stderr when it is a refusal.

pub fn plain() -> Self

A style that emits no escape sequences, whatever is attached.

pub fn is_painted(self) -> bool

Whether anything this style produces will differ from plain text.

Read by callers whose whole output is decoration: a summary that nobody is looking at is not worth the two lines it would push a real error off the top of the screen with.

pub fn bold(self, text: &str) -> String

The one word on a line that carries its meaning.

pub fn dim(self, text: &str) -> String

Context that must not compete with what it qualifies.

pub fn red(self, text: &str) -> String

A refusal.

pub fn green(self, text: &str) -> String

An acceptance.

pub fn cyan(self, text: &str) -> String

Something to type.
