Struct rtss::RtssWriter

pub struct RtssWriter<W> { /* fields omitted */ }

A writer that prefixes all lines with relative timestamps.

Implementations

impl<W: Write> RtssWriter<W>

pub fn new(
    inner: W,
    formatter: DurationFormatter,
    separator: char,
    now: Instant
) -> Self

Create a new RtssWriter, with a given start time, Duration formatter, and delimiter separating the prefix and content.

use std::io::{self, Write};
use std::time::{Duration, Instant};

extern crate rtss;
use rtss::{RtssWriter, DurationExt};

fn main() -> io::Result<()> {
    let mut writer = RtssWriter::new(io::stdout(), Duration::human_string, '|', Instant::now());
    writer.write(b"Hello!\n")?;
    writer.write(b"World!\n")?;
    Ok(())
}

// Expected output:
//   0.2μs    0.2μs | Hello!
//  84.7μs   84.6μs | World!

Trait Implementations

impl<W: Write> Write for RtssWriter<W>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes the contents of buf to the underlying writer, with time annotations for any new lines.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adapter for this instance of Write.
