Types

type ItemReader

type ItemReader interface {
	// Read reads a metadata item by its GUID identifier.
	Read(identifier [16]byte) ([]byte, error)

	// Count returns the total number of metadata items.
	Count() uint32
}

ItemReader provides interface for reading individual metadata items.

type MetadataReader

type MetadataReader interface {
	// ReadMetadata extracts all metadata from the virtual disk.
	ReadMetadata() (*types.MetadataValues, error)

	// GetValue retrieves a specific metadata value by its identifier.
	GetValue(identifier [16]byte) (interface{}, error)

	// WriteMetadata writes metadata values back (reserved for future use).
	WriteMetadata(values *types.MetadataValues) error
}

MetadataReader provides interface for reading and decoding VHDX metadata.

type Parser

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

Parser parses the VHDX metadata region and extracts structured values.

func NewParser

func NewParser(r io.ReaderAt, regionOffset int64, regionSize uint32) *Parser

NewParser creates a new metadata parser positioned at the given region offset.

func (*Parser) Parse

func (p *Parser) Parse() (*types.MetadataValues, error)

Parse reads and decodes the metadata table, returning all extracted values.
