常规错误码 errdash code [10000~20000)

Functions

func GetCodeMsg

func GetCodeMsg(code uint32) string

GetCodeMsg @Editor robotyang at 2023

GetCodeMsg 转义 code 为对应中文含义

@Param code 可能是 grpc code、errdash code 的 uint32 或 codes.Code;

func ParseCode

func ParseCode(code any) uint32

ParseCode @Editor robotyang at 2023

ParseCode 解析 code 对应的 errdash code

@Param code 可能是 grpc code、errdash code 的 uint32 或 codes.Code;

func RegisterCode

func RegisterCode(dict map[uint32]string)

RegisterCode @Editor robotyang at 2023

RegisterCode 注册错误字典

@Param dict 要注册的错误字段（建议尽量注册 >= 20000 的 code）
