The System and your Actors can LogMessage through this module.
The System itself doesn't store these log messages anywhere, It's up to you to handle and/or store these messages through an Actor.
System.Internal.Message.LogMessage addresses actors appMsg
The opaque LogMessage type
You can create LogMessages using the helper function available
emergency : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Emergency
alert : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Alert
critical : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Critical
error : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Error
warning : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Warning
notice : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Notice
info : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Informational
debug : System.Internal.PID.PID -> String -> LogMessage addresses actors appMsg
Create a new LogMessage with the severity Debug
When you create a log message through any of the create helpers your log message will not have a time accociated with it.
withPosix : LogMessage addresses actors appMsg -> Time.Posix -> LogMessage addresses actors appMsg
Add a Posix (elm/time) to your LogMessage
What was the message that resulted in this LogMessage? I don't know, but if you supply it I'll store it on the LogMessage type!
withMessage : System.Message.SystemMessage addresses actors appMsg -> LogMessage addresses actors appMsg -> LogMessage addresses actors appMsg
Supply a Message that resulted in this logMessage
You could use this to retry a failed command for instance.
toString : LogMessage addresses actors appMsg -> String
Turn a LogMessage into a String
error pid appMsg "I'm sorry Dave, I'm afraid I can't do that"
|> toString
-- error | 2(1) | I'm sorry Dave, I'm afraid I can't do that
error system appMsg "I'm sorry Dave, I'm afraid I can't do that"
|> withPosix now
|> toString
