Implementations

impl InnerNodeStats

fn aggregate_data<K, V, const PREFIX_LEN: usize, N>(&mut self, t: &N)

where N: InnerNode<PREFIX_LEN, Key = K, Value = V>,

pub fn free_slots(&self) -> usize

How many free slots

pub fn percentage_slots(&self) -> f64

Percentage of the maximum slots that is being used

pub fn avg_prefix_len(&self) -> f64

The average prefix length

pub fn avg_capped_prefix_len(&self) -> f64

The average prefix length but capped to the header prefix length

pub fn free_header_bytes(&self) -> usize

The average prefix length but capped to the header prefix length

pub fn percentage_header_bytes(&self) -> f64

The average prefix length but capped to the header prefix length

pub fn node_size(&self) -> Option<usize>

Gets the node size in bytes, if the node count is 0, than this method returns None

Trait Implementations

impl Add for InnerNodeStats

type Output = InnerNodeStats

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for InnerNodeStats

fn clone(&self) -> InnerNodeStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InnerNodeStats

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

Formats the value using the given formatter.

impl Default for InnerNodeStats

fn default() -> InnerNodeStats

Returns the “default value” for a type.

impl Hash for InnerNodeStats

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 InnerNodeStats

fn eq(&self, other: &InnerNodeStats) -> 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.
