type VFS 

type VFS interface {
}

type VFSContext 

type VFSContext struct {
}

VFSContext is a 'context' for VFS, that is normally a singleton but allows us to configure S3 credentials, for example 

var Context VFSContext

func (*VFSContext) BuildVfsPath 

func (c *VFSContext) BuildVfsPath(p string) (Path, error)

func (*VFSContext) ReadFile 

func (c *VFSContext) ReadFile(location string) ([]byte, error)

ReadLocation reads a file from a vfs URL It supports additional schemes which don't (yet) have full VFS implementations: 

metadata: reads from instance metadata on GCE/AWS
http / https: reads from HTTP

type VFSScan 

type VFSScan struct {
	Base Path
	// contains filtered or unexported fields
}

VFSScan scans a source Path for changes files

func NewVFSScan 

func NewVFSScan(base Path) *VFSScan

func (*VFSScan) Scan 

func (v *VFSScan) Scan() ([]Change, error)

Scans for changes files. On the first call will return all files as ChangeType_Added. On subsequent calls will return any changed files (using their hashes)
