Functions

func OpenFile

func OpenFile(name string, flag int, perm fs.FileMode) (*os.File, error)

OpenFile behaves the same as os.OpenFile, except on Windows it sets syscall.FILE_SHARE_DELETE.

Types

type FS

type FS struct{}

FS implements fs.FS, fs.StatFS, and fs.ReadFileFS using package os.

This filesystem does not respect fs.ValidPath rules, and fails testing/fstest.TestFS!

Still, it can be a useful tool to unify implementations that can access either the os filesystem or an fs.FS. It's OK to use this to open files, but you should avoid opening directories, resolving paths, or walking the file system.

func (FS) Open

func (FS) Open(name string) (fs.File, error)

Open implements fs.FS.

func (FS) ReadFile

func (FS) ReadFile(name string) ([]byte, error)

ReadFile implements fs.ReadFileFS.

func (FS) Stat

func (FS) Stat(name string) (fs.FileInfo, error)

ReadFileFS implements fs.StatFS.
