pub struct LogFilter { /* private fields */ }

A LogFilter supports concurrent control the log level. Use in combine with macros logger_XXX

Example

use captains_log::*;
let logger = LogFilter::new();
logger.set_level(log::Level::Error);
// info will be filtered
logger_info!(logger, "using LogFilter {}", "ok");
logger_error!(logger, "error occur");

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
