Overview

logutil包提供一个日志对象 日志对象提供一下功能：

1、提供 Panic Fatal Error Warn Info Debug Trace 七个日志级别，以及动态设置
2、支持指定日志路径与日志文件名
3、支持动态设置tag过滤

Functions

func GetCaller

func GetCaller(skip int) string

获取调用函数及行号

func GetCallerStack

func GetCallerStack(skip int) string

func Printf

func Printf(v any, alignment bool) string

Types

type Frame

type Frame uintptr

Frame represents a program counter inside a stack frame. For historical reasons if Frame is interpreted as a uintptr its value represents the program counter + 1.

func (Frame) PC

func (f Frame) PC() uintptr

PC returns the program counter for this frame; multiple frames may have the same PC value.

type Logger

type Logger struct {
	// contains filtered or unexported fields
}
