Struct LocalShard 

pub struct LocalShard {
    pub dim: usize,
    pub vectors: Vec<Vec<f32>>,
}

Single-node shard backed by an in-memory vector slice.

In production this would wrap a mmap pointer to the SSD-resident full-precision block described in storage::VamanaStorageLayout. For the current tier we hold owned Vec<Vec<f32>> so the type compiles and tests pass without io_uring plumbing.

Fields

dim: usize

Vector dimensionality.

vectors: Vec<Vec<f32>>

Dense FP32 vector storage indexed by node order.

Implementations

impl LocalShard

pub fn new(dim: usize, vectors: Vec<Vec<f32>>) -> Self

Create a LocalShard from a slice of FP32 vectors.

All vectors must have the same length (dim). The constructor is infallible; callers are expected to validate dimensions upstream.

Trait Implementations

impl Shard for LocalShard

fn dim(&self) -> usize

Vector dimensionality.

fn fetch_fp32(&self, idx: usize) -> Option<Vec<f32>>

Fetch the full-precision FP32 vector at the given node index.
