Function log4rs_gelf::init_config

pub fn init_config(config: Config) -> Result<Handle, Error>

Initializes the global logger as a log4rs logger with the provided config.

A Handle object is returned which can be used to adjust the logging configuration.

Warning

The logging system may only be initialized once.

Example

use serde_gelf::GelfLevel;
use serde_value::Value;
use log4rs::config::{Config, Appender, Root};
use log::LevelFilter;

fn main() {
   let buffer = log4rs_gelf::BufferAppender::builder()
       .set_level(GelfLevel::Informational)
       .set_hostname("localhost")
       .set_port(12202)
       .set_use_tls(false)
       .set_null_character(true)
       .set_buffer_size(Some(5))
       .set_buffer_duration(Some(5))
       .put_additional_field("component", Value::String("rust-cs".to_string()))
       .build()
       .unwrap();

   let config = Config::builder()
       .appender(Appender::builder().build("gelf", Box::new(buffer)))
       .build(Root::builder().appender("gelf").build(LevelFilter::Info))
       .unwrap();

   log4rs_gelf::init_config(config).unwrap();

   // Do whatever

   log4rs_gelf::flush().expect("Failed to send buffer, log records can be lost !");
