/**
|
|
* Helper for logging with metadata. The created object has methods similar to those of the `log`
|
|
* module, but with an extra required first argument. The produced messages get metadata produced
|
|
* by the constructor callback applied to that argument, and the specified prefix.
|
|
*
|
|
* Usage:
|
|
* _log = new LogMethods(prefix, (info) => ({...logMetadata...}))
|
|
* _log.info(info, "hello %", name);
|
|
* _log.warn(info, "hello %", name);
|
|
* etc.
