Struct BlockContentV0

pub struct BlockContentV0 {
    pub commit_header: CommitHeaderObject,
    pub children: Vec<BlockId>,
    pub encrypted_content: Vec<u8>,
}

unencrypted part of the Block

Fields

commit_header: CommitHeaderObject

Reference (actually, only its ID or an embedded block if the size is small enough) to a CommitHeader of the root Block of a commit that contains references to other objects (e.g. Commit deps & acks) Only set if the block is a commit (and it is the root block of the Object). It is an easy way to know if the Block is a commit (but be careful because some root commits can be without a header).

children: Vec<BlockId>

Block IDs for child nodes in the Merkle tree, is empty if ObjectContent fits in one block or this block is a leaf. in both cases, encrypted_content is then not empty

encrypted_content: Vec<u8>

contains encrypted ChunkContentV0 (entirely, when fitting, or chunks of ObjectContentV0, in DataChunk) used for leaves of the Merkle tree, or to store the keys of children (in InternalNode)

Encrypted using convergent encryption with ChaCha20:

• convergence_key: BLAKE3 derive_key (“NextGraph Data BLAKE3 key”, StoreRepo + store’s repo ReadCapSecret ) // basically similar to the InnerOverlayId but not hashed, so that brokers cannot do “confirmation of a file” attack
• key: BLAKE3 keyed hash (convergence_key, plain_chunk_content)
• nonce: 0

Trait Implementations

impl Clone for BlockContentV0

fn clone(&self) -> BlockContentV0

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockContentV0

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlockContentV0

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BlockContentV0

fn eq(&self, other: &BlockContentV0) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BlockContentV0

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
