pub fn timestamp(&mut self, timestamp: Timestamp) -> &mut StdErrLog

Enables or disables the use of timestamps in log messages

pub fn color(&mut self, choice: ColorChoice) -> &mut StdErrLog

Enables or disables the use of color in log messages

pub fn module<T: Into<String>>(&mut self, module: T) -> &mut StdErrLog

specify a module to allow to log to stderr

pub fn show_module_names(&mut self, show_module_names: bool) -> &mut StdErrLog

Enables or disables the use of module names in log messages

pub fn modules<T: Into<String>, I: IntoIterator<Item = T>>( &mut self, modules: I ) -> &mut StdErrLog

specify modules to allow to log to stderr

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