Struct StoreMeta 

pub struct StoreMeta {
    pub total_rows: usize,
    pub shape_tail: Vec<usize>,
    pub dtype: String,
}

Metadata about a stored value, queryable without loading data.

Fields

total_rows: usize

shape_tail: Vec<usize>

Remaining shape dimensions after the row axis (shape[1..] for tensors).

dtype: String

Type tag: “tensor”, “json”, “bytes”, or “empty”.
