Functions

func Await

func Await(p js.Value) (js.Value, error)

A helper function which makes async calls to JS API synchronous.

An example of what this does:

FileSystemDirectoryHandle.removeEntry(name).then(() => {
	// something
}).catch(() => {
	// something
});

But instead of "something", we pass the value/error to Go.

	RootHandle js.Value // FileSystemDirectoryHandle

type OPFSFile

type OPFSFile struct {
	// contains filtered or unexported fields
}

This struct represents a file in our OPFS FileSystem, but there can by multiple instances of the single file, with different offsets, pointing at the same inode (aka. the REAL file)

func (*OPFSFile) Close

func (f *OPFSFile) Close() error

func (*OPFSFile) Lock

func (f *OPFSFile) Lock() error

func (*OPFSFile) Name

func (f *OPFSFile) Name() (name string)

func (*OPFSFile) Read

func (f *OPFSFile) Read(p []byte) (int, error)

func (*OPFSFile) ReadAt

func (f *OPFSFile) ReadAt(p []byte, off int64) (n int, err error)

func (*OPFSFile) Seek

func (f *OPFSFile) Seek(offset int64, whence int) (newOffset int64, err error)

func (*OPFSFile) Truncate

func (f *OPFSFile) Truncate(size int64) error

func (*OPFSFile) Unlock

func (f *OPFSFile) Unlock() error

func (*OPFSFile) Write

func (f *OPFSFile) Write(p []byte) (int, error)

func (*OPFSFile) WriteAt

func (f *OPFSFile) WriteAt(p []byte, off int64) (n int, err error)

type OPFSFileInfo

type OPFSFileInfo struct {
	// contains filtered or unexported fields
}

func (*OPFSFileInfo) Info

func (fi *OPFSFileInfo) IsDir() bool

func (*OPFSFileInfo) ModTime

func (fi *OPFSFileInfo) ModTime() time.Time

func (*OPFSFileInfo) Mode

func (fi *OPFSFileInfo) Mode() os.FileMode

Mode returns the file permissions. Git checks this to see if a file is executable or a directory.
