Types

type LevelFilter

type LevelFilter struct {
	// Levels is the list of log levels, in increasing order of
	// severity. Example might be: {"DEBUG", "WARN", "ERROR"}.
	Levels []LogLevel

	// MinLevel is the minimum level allowed through
	MinLevel LogLevel

	// The underlying io.Writer where log messages that pass the filter
	// will be set.
	Writer io.Writer
	// contains filtered or unexported fields
}

LevelFilter is an io.Writer that can be used with a logger that will filter out log messages that aren't at least a certain level.

Once the filter is in use somewhere, it is not safe to modify the structure.

func (*LevelFilter) Write
