Struct AccessLayout 

pub struct AccessLayout {
    pub block_size: usize,
    pub lowest_block_size: usize,
    pub type_size: usize,
}

Fields

block_size: usize

The size of the block in elements.

lowest_block_size: usize

The size of the minimal block we may split into/merge from (usually 1 or 4)

type_size: usize

The size of the type in bytes (1 for u8, 4 for F).

Trait Implementations

impl Clone for AccessLayout

fn clone(&self) -> AccessLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> CustomBorrow<'a, AccessRecordMut<'a>, AccessLayout> for [u8]

fn custom_borrow(&'a mut self, layout: AccessLayout) -> AccessRecordMut<'a>

unsafe fn extract_layout(&self) -> AccessLayout

Given &self as a valid starting pointer of a reference that has already been previously allocated and written to, extracts and returns the corresponding layout. This must work even if T is not sized.

impl Debug for AccessLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> RecordArena<'a, AccessLayout, AccessRecordMut<'a>> for DenseRecordArena

fn alloc(&'a mut self, layout: AccessLayout) -> AccessRecordMut<'a>

Allocates underlying buffer and returns a mutable reference RecordMut. Note that calling this function may not call an underlying memory allocation as the record arena may be virtual.

impl SizedRecord<AccessLayout> for AccessRecordMut<'_>

fn size(layout: &AccessLayout) -> usize

The minimal size in bytes that the RecordMut requires to be properly constructed given the layout.

fn alignment(_: &AccessLayout) -> usize

The minimal alignment required for the RecordMut to be properly constructed given the layout.
