Expand description
Log record that is passed to a logger
Fields§
§id: LogID
Logging span identifier, or 0 for outside of a span
level: LogLevel
Logging level
target: &'a str
Logging target, or “”
fmt: Arguments<'a>
Freeform formatted text. This can be output with any macro
that accepts a format-string, e.g. println!("{}", fmt)

Key-value pairs. Call this function with your own
LogVisitor
and all the key-value pairs will be passed to
that visitor in sequence.
