Struct Commit 

pub struct Commit {
    pub tree: Hash,
    pub parents: Vec<Hash>,
    pub author: String,
    pub timestamp: i64,
    pub message: String,
    pub metadata: BTreeMap<String, String>,
}

a commit object pointing to a tree with metadata

Fields

tree: Hash

root tree hash

parents: Vec<Hash>

parent commit hashes (empty for initial, 1 for linear, 2+ for merge)

author: String

author identity

timestamp: i64

unix timestamp (seconds since epoch)

message: String

commit message

metadata: BTreeMap<String, String>

optional key-value metadata (uses BTreeMap for deterministic serialization)

Implementations

impl Commit

pub fn new( tree: Hash, parents: Vec<Hash>, author: impl Into<String>, message: impl Into<String>, ) -> Self

create a new commit

pub fn with_timestamp( tree: Hash, parents: Vec<Hash>, author: impl Into<String>, timestamp: i64, message: impl Into<String>, ) -> Self

create a new commit with explicit timestamp

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

add metadata key-value pair

pub fn is_root(&self) -> bool

is this an initial commit (no parents)

pub fn is_merge(&self) -> bool

is this a merge commit (multiple parents)
