Struct Branch 

pub struct Branch {
    pub name: String,
    pub parent: Option<String>,
    pub head_op: Option<OpId>,
    pub predicate: Option<Value>,
    pub merges: Vec<MergeRecord>,
    pub created_at: u64,
}

Fields

name: String

parent: Option<String>

head_op: Option<OpId>

Op DAG head. None means the branch has never had an op applied (empty branch) or it’s a predicate-defined branch where the head is computed lazily from predicate.

predicate: Option<Value>

Predicate over the op log (#133). When Some, the branch is a saved query rather than a snapshot — head_op is the optional materialization cache. The predicate’s JSON shape matches lex_vcs::Predicate::to_value().

merges: Vec<MergeRecord>

Append-only journal of merges committed into this branch.

created_at: u64

Trait Implementations

impl Clone for Branch

fn clone(&self) -> Branch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Branch

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Branch

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Branch

fn eq(&self, other: &Branch) -> 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 Branch

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
