Struct kvlogger::KvLoggerBuilder

pub struct KvLoggerBuilder { /* fields omitted */ }

A builder to create and register kvlogger

Examples

use std::error::Error;
use log::Level;
use kvlogger::*;

fn main() -> Result<(), Box<dyn Error>> {
  KvLoggerBuilder::default().init()?;

  KvLoggerBuilder::default()
    .set_level(Level::Debug)
    .set_datetime_format("%Y-%m-%d")
    .init()?;

  Ok(())
}

Implementations

impl KvLoggerBuilder

pub fn set_level(mut self: Self, level: Level) -> KvLoggerBuilder

Force the maximum log level to be printed. If not given, the value of the RUST_LOG environment variable is considered.

Defaults to Error.

pub fn set_datetime_format<S>(mut self: Self, format: S) -> KvLoggerBuilder where
    S: Into<String>, 

Change the datetime format used for timestamps

This method does not have any effect unless the datetime feature is opted into. If it is not, the datetime timestamps is replaced with the current UNIX milliseconds timestamp.

Defaults to %Y-%m-%dT%H:%M:%S.3f%z.

pub fn init(self) -> Result<(), SetLoggerError>

Finalize the builder and register the logger

This method closes the builder by moving it and registers kvlogger as the default log system for the current program.
