|

// `Entry`. It exposes all the fields, including the default ones:
|
|
//
|
|
// * `entry.Data["msg"]`. The message passed from Info, Warn, Error ..
|
|
// * `entry.Data["time"]`. The timestamp.
|
|
// * `entry.Data["level"]. The level the entry was logged at.
|
|
//
|
|
// Any additional fields added with `WithField` or `WithFields` are also in
|
|
// `entry.Data`. Format is expected to return an array of bytes which are then
|
|
// logged to `logger.Out`.

// {"level": "info", "fields.level": 1, "msg": "hello", "time": "..."}

|
// It's not exported because it's still using Data in an opinionated way. It's to

// avoid code duplication between the two default formatters.
