Struct MatrixSliceData 

pub struct MatrixSliceData {
    pub parent: Arc<MatrixData>,
    pub offset: u32,
    pub len: u32,
}

Row/column projection into a parent MatrixData ({ parent, offset, len }).

ADR-006 §2.7.22 amendment (Round 18 S3 W12-matrix-floatslice-heapkind-exit, 2026-05-13): FloatSlice exits the TypedArrayData carrier hierarchy as a category-error. It is a projection-into-a-Matrix, not a buffer of floats. The carrier is Arc<MatrixSliceData> with kind Ptr(HeapKind::MatrixSlice), constructed by Matrix.row(i) / Matrix.col(i) projection methods.

Aliasing semantics: the projection shares the parent Matrix’s buffer (mutating through the projection writes through to the parent), preserved from the pre-amendment TypedArrayData::FloatSlice shape. The parent Arc retains one strong-count share for the projection’s lifetime.

Fields

parent: Arc<MatrixData>

offset: u32

len: u32
