Construction

defaultLogSettings :: LogSettings

Modify

setLogSettingsLevels :: LogLevels -> LogSettings -> LogSettings

setLogSettingsDestination :: LogDestination -> LogSettings -> LogSettings

setLogSettingsFormat :: LogFormat -> LogSettings -> LogSettings

setLogSettingsColor :: LogColor -> LogSettings -> LogSettings

setLogSettingsBreakpoint :: Int -> LogSettings -> LogSettings

setLogSettingsConcurrency :: Maybe Int -> LogSettings -> LogSettings

Set the number of LoggerSet Buffers used by fast-logger

By default this matches getNumCapabilities, which is more performant but does not guarantee message order. If this matters, such as in a CLI, set this value to 1.

Support for this option depends on your version of fast-logger:

fast-logger | Destination	Supported?
>=3.1.1 | anywhere	yes
>=3.0.5 | file	yes
>=3.0.5 | stdout/stderr	no
<3.0.5 | anywhere	no
