Functions ¶
func CopyFile ¶
CopyFile copies from src to dst until either an error occurs. It returns the number of bytes copied and the first error encountered while copying, if any.
A successful CopyFile returns err == nil, not err == EOF. Because CopyFile is defined to read from src until EOF, it does not treat an EOF from Read as an error to be reported.
func CopyFileWatcher ¶
func CopyFileWatcher(dst string, src string, buf []byte, listener IOProgressListener) (written int64, err error)
CopyFileWatcher is identical to CopyBuffer except that it provided listener (if one is required).
func CreateFolder ¶
func FileExists ¶
func FileNameWithoutExt ¶
FileNameWithoutExt filename without extension
func FolderExists ¶
func GenUniqueFilename ¶
GenUniqueFilename filename exists return new name rule custom name rule
func GetGoroutineId ¶
func GetGoroutineId() uint64
func MoveFile ¶
MoveFile move from src to dst until either an error occurs. It returns the number of bytes move and the first error encountered while moving, if any.
A successful MoveFile returns err == nil, not err == EOF. Because MoveFile is defined to read from src until EOF, it does not treat an EOF from Read as an error to be reported.
func MoveFileWatcher ¶
func MoveFileWatcher(dst string, src string, buf []byte, listener IOProgressListener) (written int64, err error)
MoveFileWatcher is identical to CopyFileWatcher except that it remove the source file when completes
func ReadFileAt ¶
ReadFileAt reads bytes from the File starting at byte offset off. It returns bytes and the error, if any. ReadAt always returns a non-nil error when size != len(b). At end of file, that error is io.EOF.
Types ¶
type FileInfo ¶
type FileInfo struct {
Name string
Path string
Mime types.Type
Head []byte
Width float64
Height float64
Stat os.FileInfo
}
func GetFileInfo ¶
GetFileInfo returns a FileInfo describing the named file. If there is an error, fi = nil.
type IOProgressListener ¶
type IOProgressListener interface {
ProgressChanged(event *ProgressEvent)
}
type ProgressEvent ¶
type ProgressEvent struct {
ConsumedBytes int64
TotalBytes int64
EventType ProgressEventType
}
type ProgressEventType ¶
type ProgressEventType int
const ( // TransferStartedEvent transfer started, set TotalBytes TransferStartedEvent ProgressEventType = 1 + iota // TransferDataEvent transfer data, set ConsumedBytes anmd TotalBytes TransferDataEvent // TransferCompletedEvent transfer completed TransferCompletedEvent // TransferFailedEvent transfer encounters an error TransferFailedEvent )
