type FS ¶

type FS struct {
	Files map[string]File
	Dirs  map[string]iofs.FileMode
	Errs  map[string]error
}

Provide the in-memory implementation of the internal FS interface.

This is a simple in-memory filesystem that can be used for testing. It is not thread-safe. There are two ways to use this:

1. Use the New() function to create a new FS instance and then use the WithFile() and WithError() options to populate the filesystem.
2. Create a FS instance and then populate the Files, Dirs, and Errs fields directly.

func New(opts ...Option) *FS

func (fs *FS) Mkdir(path string, perm iofs.FileMode) error

func (fs *FS) MkdirAll(path string, perm iofs.FileMode) error

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

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

func (fs *FS) WriteFile(name string, data []byte, perm iofs.FileMode) error

type File ¶

type File struct {
	Bytes []byte
	Perm  iofs.FileMode
	// contains filtered or unexported fields
}

File is an in-memory implementation of the iofs.File interface.

func (f *File) Close() error

func (f *File) Read(b []byte) (int, error)

func (f *File) Stat() (iofs.FileInfo, error)

type Option ¶

type Option func(*FS)

Option is a functional option for creating a MemFS instance.

func WithDir(name string, perm iofs.FileMode) Option

func WithError(name string, err error) Option

func WithFile(name, data string, perm iofs.FileMode) Option
