GetFileCategoryByDet returns the FileCategory for a given detection string.
func GetFileCategoryByExt ¶
func GetFileCategoryByExt(ext string) FileCategory
GetFileCategoryByExt returns the FileCategory for a given file extension.
func (FileCategory) Ok ¶
func (t FileCategory) Ok(filepath string) bool
The Ok function determines whether the given file path belongs to the specified file category. Parameters:
- filepath: File path
Return value:
- bool: Returns true if the file path is of the specified file category; otherwise, returns false.
func (FileCategory) OkBs ¶ added in v0.3.15
func (t FileCategory) OkBs(r []byte) bool
OkBs checks if the given byte slice belongs to the specified file category. It first detects the content type of the byte slice using FileTypeByDetectContentType. Then it checks if the detected file category matches the specified file category. Returns true if the byte slice belongs to the specified file category, otherwise false.
func (FileCategory) OkRead ¶
func (t FileCategory) OkRead(r io.Reader) bool
The OkRead function determines whether the content from the provided io.Reader belongs to the specified file category. Parameters:
- r: io.Reader
Return value:
- bool: Returns true if the content from the io.Reader is of the specified file category; otherwise, returns false.
