Function init

pub fn init(is_critical: bool) -> Result<()>

Initializes the DLog logging system.

This function sets up the logging infrastructure by configuring the logger for the current application. It should be called once.

Under the hood, there is a struct with Log trait implemented that uses dlog_print for sending logs to DLog. If invoked with is_critical = true, it sends critical logs instead.

Priority of a log is defined by a macro used and tag is constructed from the binary name. However, it can be overwritten - see example below.

Errors

• std::io::ErrorKind::Other - Wrapped error from set_boxed_logger.

Examples

Sending non-critical logs:

use log::info;

fn main() -> Result<(), std::io::Error> {
    dlog::init(false)?;
    info!("my first log");
}

Sending critical logs:

use log::info;

fn main() -> Result<(), std::io::Error> {
    dlog::init(true)?;
    info!("my first critical log");
}

You can set your custom tag by setting target argument:

use log::info;

fn main() -> Result<(), std::io::Error> {
    dlog::init(false)?;
    info!(target: "my_tag", "my first log with a custom tag");
}
