Types

type AddPathOptions added in v0.3.0 

type AddPathOptions struct {
	SkipBrokenSymlinks bool     // skip broken symlinks instead of erroring
	FollowSymlinks     bool     // follow symlinks and store target content (default false = store as symlinks)
	ExcludePatterns    []string // glob patterns to exclude (matched against basename)
}

AddPathOptions configures the behaviour of AddPath.

type DataNode 

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

DataNode is an in-memory filesystem that is compatible with fs.FS.

func FromTar 

func FromTar(tarball []byte) (*DataNode, error)

FromTar creates a new DataNode from a tarball.

func New 

func New() *DataNode

New creates a new, empty DataNode.

func (*DataNode) AddData 

func (d *DataNode) AddData(name string, content []byte)

AddData adds a file to the DataNode.

func (*DataNode) AddPath added in v0.3.0 

func (d *DataNode) AddPath(dir string, opts AddPathOptions) error

AddPath walks a real directory and adds its files to the DataNode. Paths are stored relative to dir, normalized with forward slashes. Directories are implicit and not stored. 

func (d *DataNode) AddSymlink(name, target string)

AddSymlink adds a symlink entry to the DataNode.

func (*DataNode) CopyFile 

func (d *DataNode) CopyFile(sourcePath string, target string, perm os.FileMode) error

CopyFile copies a file from the DataNode to the local filesystem.

func (*DataNode) Exists 

func (d *DataNode) Exists(name string, opts ...ExistsOptions) (bool, error)

Exists returns true if the file or directory exists.

func (*DataNode) Open 

func (d *DataNode) Open(name string) (fs.File, error)

Open opens a file from the DataNode.

func (*DataNode) ReadDir 

func (d *DataNode) ReadDir(name string) ([]fs.DirEntry, error)

ReadDir reads and returns all directory entries for the named directory.

func (*DataNode) Stat 

func (d *DataNode) Stat(name string) (fs.FileInfo, error)

Stat returns the FileInfo structure describing file.

func (*DataNode) ToTar 

func (d *DataNode) ToTar() ([]byte, error)

ToTar serializes the DataNode to a tarball.

func (*DataNode) ToTarWriter added in v0.3.0 

func (d *DataNode) ToTarWriter(w io.Writer) error

ToTarWriter streams the DataNode contents to a tar writer. File keys are sorted for deterministic output.

func (*DataNode) Walk 

func (d *DataNode) Walk(root string, fn fs.WalkDirFunc, opts ...WalkOptions) error

Walk recursively descends the file tree rooted at root, calling fn for each file or directory.

type ExistsOptions 

type ExistsOptions struct {
	WantType fs.FileMode
}

ExistsOptions allows customizing the Exists check.

type WalkOptions 

type WalkOptions struct {
	MaxDepth   int
	Filter     func(path string, d fs.DirEntry) bool
	SkipErrors bool
}

WalkOptions allows customizing the Walk behavior.
