Struct mz_repr::row::columnation::RowStack

source ·
pub struct RowStack {
    region: LgAllocRegion<u8>,
}
Expand description

Region allocation for Row data.

Content bytes are stored in stable contiguous memory locations, and then a Row referencing them is falsified.

Fields§

§region: LgAllocRegion<u8>
