Struct LogFilter 

pub struct LogFilter { /* private fields */ }

LogFilter supports concurrent control the log level filter with atomic.

Used in combine with macros logger_XXX. the log level filter can be dynamic changed.

Example

use std::sync::Arc;
use captains_log::{*, filter::LogFilter};
log::set_max_level(log::LevelFilter::Debug);
let logger_io = Arc::new(LogFilter::new());
let logger_req = Arc::new(LogFilter::new());
logger_io.set_level(log::Level::Error);
logger_req.set_level(log::Level::Debug);
logger_debug!(logger_req, "Begin handle req ...");
logger_debug!(logger_io, "Issue io to disk ...");
logger_error!(logger_req, "Req invalid ...");

Implementations

impl LogFilter

pub fn new() -> Self

pub fn set_level(&self, level: Level)

When LogFilter is shared in Arc, allows concurrently changing log level filter

pub fn get_level(&self) -> usize
