Collection of stats about the number of nodes types present in a tree

Fields

node4: InnerNodeStats

Stats for InnerNode4s

node16: InnerNodeStats

Stats for InnerNode16s

node48: InnerNodeStats

Stats for InnerNode48s

node256: InnerNodeStats

Stats for InnerNode256s

tree: InnerNodeStats

Stats for the whole tree

leaf: LeafStats

Number of LeafNodes present in the tree.

Implementations

impl TreeStats

pub fn total_memory_usage(&self) -> usize

Total memory usage of the tree (inner nodes + leaf)

pub fn bytes_per_entry(&self) -> f64

Bytes used per entry in the tree (only inner node memory usage)

pub fn bytes_per_entry_with_leaf(&self) -> f64

Bytes used per entry in the tree (total memory usage)

Trait Implementations

impl Clone for TreeStats

fn clone(&self) -> TreeStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreeStats

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

Formats the value using the given formatter.

impl Default for TreeStats

fn default() -> TreeStats

Returns the “default value” for a type.

impl Display for TreeStats

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

Formats the value using the given formatter.

impl Hash for TreeStats

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TreeStats

fn eq(&self, other: &TreeStats) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for TreeStats
