var MaxFileBytes int64 = 256 * 1024 * 1024 // 256 MiB

MaxFileBytes is the maximum file bytes. When used, the value should be strictly less than this number.

Functions

func CopyFromReaderToDir

func CopyFromReaderToDir(src io.Reader, dst string, perm fs.FileMode) error

CopyFromReaderToDir copies file from src to dst where dst is the destination file path.

func CopyToDir

func CopyToDir(src, dst string) (int64, error)

CopyToDir copies the src file to dst. Existing file will be overwritten.

func DetectFileType

func DetectFileType(path string) (string, error)

DetectFileType returns a file's content type given path

func IsRegularFile

func IsRegularFile(path string) (bool, error)

IsRegularFile checks if path is a regular file

func ValidateSHA256Sum

func ValidateSHA256Sum(path string, checksum string) error

ValidateSHA256Sum returns nil if SHA256 of file at path equals to checksum.

func WriteFile

func WriteFile(path string, data []byte) error

WriteFile writes to a path with all parent directories created.

func WriteFileWithPermission

func WriteFileWithPermission(path string, data []byte, perm fs.FileMode, overwrite bool) error
