// Package log provides logging capabilities for Gitea.
// Concepts:
//
// * Logger: a Logger provides logging functions and dispatches log events to all its writers
//
// * EventWriter: written log Event to a destination (eg: file, console)
// - EventWriterBase: the base struct of a writer, it contains common fields and functions for all writers
// - WriterType: the type name of a writer, eg: console, file
// - WriterName: aka Mode Name in document, the name of a writer instance, it's usually defined by the config file.
// It is called "mode name" because old code use MODE as config key, to keep compatibility, keep this concept.
//
// * WriterMode: the common options for all writers, eg: log level.
// - WriterConsoleOption and others: the specified options for a writer, eg: file path, remote address.
//
// Call graph:
// -> log.Info()
// -> LoggerImpl.Log()
// -> LoggerImpl.SendLogEvent, then the event goes into writer's goroutines
// -> EventWriter.Run() handles the events
package log
// BaseLogger provides the basic logging functions
type BaseLogger interface {
Log(skip int, level Level, format string, v ...any)

// LevelLogger provides level-related logging functions
