Lowlevel android sparse image parsing helpers

An android space image is a sparse representation of a potential output file. The format consist of a FileHeader followed by a number of ChunkHeaders and their associated data

Sparse image
File header
Chunk 0 header
Chunk 0 data
Chunk 1 header
Chunk 1 data
….
Chunk N header
Chunk N data

The size of data in a chunk depends on the ChunkType and can be determined with ChunkHeader::data_size

Structs

• ChunkHeader
  Header of a chunk
• FileHeader
  Global file header

Enums

• ChunkType
  Type of a chunk
• ParseError
  Byte parsing errors

Constants

• CHUNK_HEADER_BYTES_LEN
  Length of the chunk header in bytes
• FILE_HEADER_BYTES_LEN
  Length of the file header in bytes
• HEADER_MAGIC
  File magic - This are the first 4 bytes in little-endian

Type Aliases

• ChunkHeaderBytes
  Byte array which fits a chunk header
• FileHeaderBytes
  Byte array which fits a file header
