Struct simplelog::TermLogger

pub struct TermLogger { /* fields omitted */ }

The TermLogger struct. Provides a stderr/out based Logger implementation

Supports colored output

Methods

impl TermLogger

pub fn init(log_level: LevelFilter, config: Config) -> Result<(), TermLogError>

init function. Globally initializes the TermLogger as the one and only used log facility.

Takes the desired Level and Config as arguments. They cannot be changed later on. Fails if another Logger was already initialized.

Examples

let _ = TermLogger::init(LevelFilter::Info, Config::default());

pub fn new(log_level: LevelFilter, config: Config) -> Option<Box<TermLogger>>

allows to create a new logger, that can be independently used, no matter whats globally set.

no macros are provided for this case and you probably dont want to use this function, but init(), if you dont want to build a CombinedLogger.

Takes the desired Level and Config as arguments. They cannot be changed later on.

Examples

let term_logger = TermLogger::new(LevelFilter::Info, Config::default()).unwrap();
