Function grep_cli::stdout

Important traits for StandardStream

impl Write for StandardStream

pub fn stdout(color_choice: ColorChoice) -> StandardStream

Returns a possibly buffered writer to stdout for the given color choice.

The writer returned is either line buffered or block buffered. The decision between these two is made automatically based on whether a tty is attached to stdout or not. If a tty is attached, then line buffering is used. Otherwise, block buffering is used. In general, block buffering is more efficient, but may increase the time it takes for the end user to see the first bits of output.

If you need more fine grained control over the buffering mode, then use one of stdout_buffered_line or stdout_buffered_block.

The color choice given is passed along to the underlying writer. To completely disable colors in all cases, use ColorChoice::Never.
