Struct Commit 

pub struct Commit {
    pub cid: Option<Cid>,
    pub parents: Vec<Cid>,
    pub root: Cid,
    pub message: String,
    pub author: Author,
    pub timestamp: u64,
    pub metadata: HashMap<String, String>,
}

IPLD schema for a commit in the version control system

Fields

cid: Option<Cid>

CID of the commit (computed from serialized commit, not included in serialization)

parents: Vec<Cid>

CIDs of parent commits (empty for initial commit)

root: Cid

CID of the root block this commit points to (e.g., model weights)

message: String

Commit message describing the changes

author: Author

Author of the commit

timestamp: u64

Unix timestamp when commit was created

metadata: HashMap<String, String>

Optional metadata (e.g., training config, hyperparameters)

Implementations

impl Commit

pub fn new( parents: Vec<Cid>, root: Cid, message: String, author: Author, metadata: HashMap<String, String>, ) -> Self

Create a new commit

pub fn finalize(&mut self) -> Result<Cid>

Serialize commit to bytes and compute CID

pub fn from_block(block: &Block) -> Result<Self>

Create a commit from a block

pub fn to_block(&self) -> Result<Block>

Convert commit to a block for storage

pub fn is_initial(&self) -> bool

Check if this is an initial commit (no parents)

pub fn cid(&self) -> &Cid

Get a reference to the commit CID (panics if not finalized)

Trait Implementations

impl Clone for Commit

fn clone(&self) -> Commit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Commit

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Commit

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Commit

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

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

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 Commit

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
