Struct NodeSplitManifest 

pub struct NodeSplitManifest {
    pub node_id: String,
    pub total_rows: u64,
    pub train_rows: u64,
    pub test_rows: u64,
    pub validation_rows: Option<u64>,
    pub label_distribution: Option<HashMap<String, u64>>,
    pub split_hash: [u8; 32],
}

Per-node split manifest (shared with coordinator, no raw data)

Fields

node_id: String

Unique node identifier

total_rows: u64

Total rows in dataset

train_rows: u64

Rows in training split

test_rows: u64

Rows in test split

validation_rows: Option<u64>

Rows in validation split (optional)

label_distribution: Option<HashMap<String, u64>>

Label distribution (for stratification verification)

split_hash: [u8; 32]

Hash of split indices (for reproducibility verification)

Implementations

impl NodeSplitManifest

pub fn new( node_id: impl Into<String>, total_rows: u64, train_rows: u64, test_rows: u64, ) -> Self

Create a new manifest from split results

pub fn with_validation(self, rows: u64) -> Self

Set validation rows

pub fn with_label_distribution(self, distribution: HashMap<String, u64>) -> Self

Set label distribution

pub fn with_split_hash(self, hash: [u8; 32]) -> Self

Set split hash

pub fn from_split(node_id: impl Into<String>, split: &DatasetSplit) -> Self

Create manifest from a dataset split

pub fn to_json(&self) -> Result<Vec<u8>>

Serialize to JSON bytes

pub fn from_json(data: &[u8]) -> Result<Self>

Deserialize from JSON bytes

Trait Implementations

impl Clone for NodeSplitManifest

fn clone(&self) -> NodeSplitManifest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeSplitManifest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeSplitManifest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NodeSplitManifest

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
