Module asuran_core::repository::chunk

The Chunk is the lowest level of abstraction in an asuran repository.

Chunks are raw binary blobs, optionally compressed and encrypted, and keyed by an HMAC of their plain text contents, and tagged with an HMAC of their encrypted contents (different keys are used for both HMACs).

They can contain any arbitrary sequence of bytes.

Structs

ChunkHeader	A split representation of a Chunk's 'header' or metadata. Used for on disk storage
ChunkID	Key used for indexing a Chunk in a repository
ChunkSettings	Encapsulates the Encryption, Compression, and HMAC tags for a chunk
UnpackedChunk	A binary blob that has not yet undergone encryption, compression, or HMAC, but has had a ChunkID generated.
