Struct DistributedArray 

pub struct DistributedArray {
    pub rank: usize,
    pub global_len: usize,
    pub offset: usize,
    pub data: Vec<f64>,
}

A distributed scalar array owned by one rank.

Fields

rank: usize

MPI rank that owns this shard.

global_len: usize

Global length of the full array.

offset: usize

Global start index of this shard.

data: Vec<f64>

Local data values.

Implementations

impl DistributedArray

pub fn new( rank: usize, global_len: usize, offset: usize, data: Vec<f64>, ) -> Self

Create a new shard.

pub fn local_len(&self) -> usize

Local length of this shard.

pub fn serialize_text(&self) -> String

Serialise to a compact binary-hex text format.

Format: rank offset global_len n_values <hex-encoded f64s>\n

pub fn deserialize_text(s: &str) -> Option<Self>

Deserialise from the text format produced by serialize_text.

pub fn assemble(shards: &[DistributedArray]) -> Option<Vec<f64>>

Reconstruct the global array by assembling shards in offset order.

All shards must cover the entire global range without gaps or overlaps.

Trait Implementations

impl Clone for DistributedArray

fn clone(&self) -> DistributedArray

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DistributedArray

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

Formats the value using the given formatter.
