Struct simplelog::WriteLogger
[−]
[src]
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>
[src]
fn init(
log_level: LogLevelFilter,
config: Config,
writable: W
) -> Result<(), SetLoggerError>
[src]
log_level: LogLevelFilter,
config: Config,
writable: W
) -> Result<(), SetLoggerError>
init function. Globally initializes the WriteLogger as the one and only used log facility.
Takes the desired LogLevel
, Config
and Write
struct as arguments. They cannot be changed later on.
Fails if another Logger was already initialized.
Examples
let _ = WriteLogger::init(LogLevelFilter::Info, Config::default(), File::create("my_rust_bin.log").unwrap());
fn new(
log_level: LogLevelFilter,
config: Config,
writable: W
) -> Box<WriteLogger<W>>
[src]
log_level: LogLevelFilter,
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 LogLevel
, Config
and Write
struct as arguments. They cannot be changed later on.
Examples
let file_logger = WriteLogger::new(LogLevelFilter::Info, Config::default(), File::create("my_rust_bin.log").unwrap());
