Function mz_repr::datums_size_deterministic

pub fn datums_size_deterministic<'a, I, D, const VAR: bool>(iter: I) -> usizewhere
    I: IntoIterator<Item = D>,
    D: Borrow<Datum<'a>>,

Number of bytes required by a sequence of datums.

This method can be used to right-size the allocation for a Row before calling RowPacker::extend.
