Struct poly_logger::StderrLogger

pub struct StderrLogger {}

Implements a GenLogger that outputs to Stderr

Simple Example

Instantiates a logger with default message and timestamp format

use log::info;
use log::LevelFilter;
use poly_logger::StderrLogger;

let mut logger = StderrLogger::new(LevelFilter::Info);
logger.init().unwrap();
info!("This is an INFO message");

Customized Example

Implements with custom timestamp format and message format

use log::info;
use log::LevelFilter;
use poly_logger::StderrLogger;

let mut logger = StderrLogger::new(LevelFilter::Info);
logger.timestamp_format("%X%.6f")
      .msg_format("[{timestamp} {file}:{line}] - {level} - {args}");
logger.init().unwrap();
info!("This is an INFO message with custom formatting");

Note

The call to new() is actually returning an instance of GenLogger. The StderrLogger struct is just a way to instantiate a GenLogger with Stderr as the target for output. See GenLogger for the full list of methods that can be called on the logger instance.
