data RequestLoggerSettings Source #

RequestLoggerSettings is an instance of Default. See Data.Default for more information.

outputFormat, autoFlush, and destination are record fields for the record type RequestLoggerSettings, so they can be used to modify settings values using record syntax.

outputFormat :: RequestLoggerSettings -> OutputFormat Source #

Default value: Detailed True.

autoFlush :: RequestLoggerSettings -> Bool Source #

Only applies when using the Handle constructor for destination.

Default value: True.

type Callback = LogStr -> IO () Source #

data IPAddrSource :: * #
