Struct OutputWriter

pub struct OutputWriter { /* private fields */ }

Writer for printing to stdout and stderr

Printing in handlers should be done through OutputWriter, which automatically uses the configured out and err colors. It also records output in commands so that it can be collected into CmdOutput

fn hello(mut out: StateMut<OutputWriter>) -> anyhow::Result<()> {
    out.println("Hello")?;
    Ok(())
}

Implementations

impl OutputWriter

pub fn new(out_style: ContentStyle, err_style: ContentStyle) -> OutputWriter

pub fn eprint<T>(&mut self, s: T) -> Result<(), Error>

where T: Display,

Prints to stderr and appends a newline character

pub fn eprintln<T>(&mut self, s: T) -> Result<(), Error>

where T: Display,

Calls eprint, then prints a newline

pub fn print<T>(&mut self, s: T) -> Result<(), Error>

where T: Display,

Prints to stdout using out_style for styling.

pub fn println<T>(&mut self, s: T) -> Result<(), Error>

where T: Display,

Calls print, then prints a newline.

pub fn print_buf(&mut self, buf: StyledBuf) -> Result<(), Error>

Prints a StyledBuf to stdout. If there are multiple lines, if will print \r\n between them.
