ShardedArray

scirs2_io::distributed::sharding

Struct ShardedArray 

Source 
pub struct ShardedArray { /* private fields */ }
Expand description

A large array of f64 values partitioned across multiple binary shard files.

Each shard file stores raw little-endian f64 values (no header). A companion <prefix>_meta.json records the layout.

Implementations§

Source§

impl ShardedArray

Source

pub fn new(config: ShardConfig) -> Self

Create a ShardedArray bound to the given config (does not touch disk yet).

Source

pub fn write(&mut self, data: &[f64]) -> Result<ShardedArrayMeta>

Write data to disk as shards.

Returns the resulting metadata.

Source

pub fn read(&self) -> Result<Vec<f64>>

Read back all shards and return the reconstructed Vec<f64>.

For Range strategy the order is preserved (contiguous blocks). For RoundRobin/Hash strategies, a reconstruction pass restores order.
