fn clone(&self) -> EAVOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EAVOrder

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

impl KeySchema<TRIBLE_LEN> for EAVOrder

const SEGMENT_PERM: &'static [usize]

Order of segments from key layout to tree layout.

const KEY_TO_TREE: [usize; 64]

Maps each key index to its position in the tree view.

const TREE_TO_KEY: [usize; 64]

Maps each tree index to its position in the key view.

type Segmentation = TribleSegmentation

The segmentation this ordering operates over.

fn tree_ordered(key: &[u8; KEY_LEN]) -> [u8; KEY_LEN]

Reorders the key from the shared key ordering to the tree ordering.

fn key_ordered(tree_key: &[u8; KEY_LEN]) -> [u8; KEY_LEN]

Reorders the key from the tree ordering to the shared key ordering.

fn segment_of_tree_depth(at_depth: usize) -> usize

Return the segment index for the byte at at_depth in tree ordering.

fn same_segment_tree(a: usize, b: usize) -> bool

Return true if the tree-ordered bytes at a and b belong to the same logical segment.
