pub fn encode_sparse_row(
columns: &[Column],
primary_key_index: usize,
row: &SparseRow,
) -> Vec<u8> ⓘExpand description
Encode one standalone sparse row canonically (SPEC.md §2.4, RFC §6.1). A row that does not match the column table, or that omits the primary key, is encoder misuse and panics (the full-row codec traps the same misuse).
