Struct simplelog::WriteLogger

pub struct WriteLogger<W: Write + Send + 'static> { /* fields omitted */ }

The WriteLogger struct. Provides a Logger implementation for structs implementing Write, e.g. File

Methods

impl<W: Write + Send + 'static> WriteLogger<W>

pub fn init(
    log_level: LevelFilter,
    config: Config,
    writable: W
) -> Result<(), SetLoggerError>

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

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

Examples

let _ = WriteLogger::init(LevelFilter::Info, Config::default(), File::create("my_rust_bin.log").unwrap());

pub fn new(
    log_level: LevelFilter,
    config: Config,
    writable: W
) -> Box<WriteLogger<W>>

allows to create a new logger, that can be independently used, no matter what is 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, Config and Write struct as arguments. They cannot be changed later on.

Examples

let file_logger = WriteLogger::new(LevelFilter::Info, Config::default(), File::create("my_rust_bin.log").unwrap());
