Struct logosaurus::LoggerBuilder

pub struct LoggerBuilder { /* fields omitted */ }

Builder for Logger.

Use Logger:builder() to obtain a LoggerBuilder.

Unmodified or unset values in the builder will default to the values used by Logger::default().

Example

use log;
use logosaurus::{Logger, L_STD, L_SHORT_FILE};
use std::io;

let mut builder = Logger::builder();
let logger = builder.set_level(log::LevelFilter::Debug)
                .set_out(Box::new(io::stderr()))
                .set_flags(L_STD | L_SHORT_FILE)
                .set_prefix("myprogram: ")
                .build();
