log2 is an out-of-the-box logging library for Rust. It writes to stdout or to file asynchronousely,
and automatically rotates based on file size.
cargo add log2
```rust use log2:*;
fn main() { log2::start();
trace!("send order request to server");
debug!("receive order response");
info!("order was executed");
warn!("network speed is slow");
error!("network connection as broken");
} ```
Output
log2 with default file size 50MB, max file count 10, you can change as you like. Note the _log2 will
stop the log2 when it is out the scope.
```rust use log2::*;
fn main() { // configurable way: // - log to file, file size: 100 MB, rotate: 20 // - tee to stdout let _log2 = log2::open("log.txt") .size(10010241024) .rotate(20) .tee(true) .start();
// out-of-the-box way
// let _log2 = log2::open("log.txt").start();
trace!("send order request to server");
debug!("receive order response");
info!("order was executed");
warn!("network speed is slow");
error!("network connection as broken");
}
```
