Struct mz_repr::row::columnation::RowStack

pub struct RowStack {
    region: LgAllocRegion<u8>,
}

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>

Implementations

impl RowStack

const LIMIT: usize = 2_097_152usize

Trait Implementations

impl Default for RowStack

fn default() -> Self

Returns the “default value” for a type.

impl Region for RowStack

type Item = Row

The type of item the region contains.

fn clear(&mut self)

Retain allocations but discard their contents.

unsafe fn copy(&mut self, item: &Row) -> Row

Add a new element to the region.

fn reserve_items<'a, I>(&mut self, items: I)

where Self: 'a, I: Iterator<Item = &'a Self::Item> + Clone,

Ensure that the region can absorb items without reallocation.

fn reserve_regions<'a, I>(&mut self, regions: I)

where Self: 'a, I: Iterator<Item = &'a Self> + Clone,

fn heap_size(&self, callback: impl FnMut(usize, usize))

Determine this region’s memory used and reserved capacity in bytes.

fn with_capacity_items<'a, I>(items: I) -> Self

where Self: 'a, I: Iterator<Item = &'a Self::Item> + Clone,

Allocate an instance of Self that can absorb items without reallocation.

fn with_capacity_regions<'a, I>(regions: I) -> Self

where Self: 'a, I: Iterator<Item = &'a Self> + Clone,

Allocate an instance of Self that can absorb the items of regions without reallocation.
