Copier for golang, copy value from struct to struct. Extends structmapper(https://github.com/structmapper/structmapper)
- overwrite 支持在已有对象上增量复制，仅支持 struct to struct
- transformer 支持在复制过程中的自定义处理，支持多级
- reset different field name 支持不同名字段复制

go-pusher is a tool that can help you upload files to oss and backup file to vps regularly.
- upload file to OSS if the file does not exist in OSS or the file in OSS is different from the local file
- backup local file to VPS regularly
