Struct MatrixWrapper 

pub struct MatrixWrapper {
    pub inner: UnsafeCell<Matrix>,
}

Thread-safe wrapper around Matrix for concurrent training

Uses UnsafeCell to allow interior mutability across threads. Safety is ensured by the training algorithm’s access patterns where each thread writes to distinct rows.

Fields

• inner - The inner matrix data (unsafe cell)

Fields

inner: UnsafeCell<Matrix>

Trait Implementations

impl Debug for MatrixWrapper

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

Formats the value using the given formatter.

impl Sync for MatrixWrapper

SAFETY: This is intentionally unsound. Multiple threads will concurrently read and write overlapping rows (e.g. a target in one thread may be a negative sample in another). This mirrors the deliberate data race in Mikolov’s original word2vec C implementation and the word2vec-rs crate it was ported from. SGD tolerates stale/torn reads and the resulting embeddings converge in practice. Do not use MatrixWrapper as a general- purpose concurrent container.
