pub(api) data log

Thread safety. safe from any task; records of different tasks may interleave, each one is written whole.

Since. 1.0.0-beta

Methods

`trace`	`(msg: str) io` Very detailed diagnostics.
`debug`	`(msg: str) io` Diagnostics for developers.
`info`	`(msg: str) io` Normal events worth recording.
`warn`	`(msg: str) io` Something unexpected that the program handled.
`error`	`(msg: str) io` An operation failed.
`at`	`(level: Level, msg: str) io` Logs at a level chosen at run time (log.at(Level.Warn, "…")).
`level`	`() -> Level io` Current threshold
`setLevel`	`(level: Level) io` Changes the threshold of this process (the start-up value comes from --log-level / OXL_LOG).
`enabled`	`(level: Level) -> bool io` True when a record at level would be written; guard expensive field computation with it.
`setJson`	`(on: bool) io` Switches between text (false) and JSON-lines (true) output.
`isJson`	`() -> bool io` True when the output is JSON lines.
