def self.new(io = STDOUT, *, formatter : Formatter = ShortFormat, dispatcher : Dispatcher::Spec = DispatchMode::Async)Source

Instance Method Detail

def format(entry : Entry) : NilSource

Emits the entry to the given io. It uses the #formatter to convert.

def formatter : FormatterSource

def formatter=(formatter : Formatter)Source

def io : IOSource

def io=(io : IO)Source

def write(entry : Entry) : NilSource

Description copied from class Log::Backend
