Struct Level

pub struct Level(/* private fields */);

A type-safe wrapper for indexing into “levels” of a binary tree, such that nodes at level 0 are leaves, nodes at level 1 are parents of nodes at level 0, and so forth. This type is capable of representing levels in trees containing up to 2^255 leaves.

Implementations

impl Level

pub const ZERO: Self = _

Level 0 corresponds to a leaf of the tree.

pub const fn new(value: u8) -> Self

pub fn iter_to(self, other: Level) -> impl Iterator<Item = Self>

Trait Implementations

impl Add<u8> for Level

type Output = Level

The resulting type after applying the + operator.

fn add(self, value: u8) -> Self

Performs the + operation.

impl Clone for Level

fn clone(&self) -> Level

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl From<Level> for u32

fn from(level: Level) -> u32

Converts to this type from the input type.

impl From<Level> for u64

fn from(level: Level) -> u64

Converts to this type from the input type.

impl From<Level> for u8

fn from(level: Level) -> u8

Converts to this type from the input type.

impl From<Level> for usize

fn from(level: Level) -> usize

Converts to this type from the input type.

impl From<u8> for Level

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for Level

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 Ord for Level

fn cmp(&self, other: &Level) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Level

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

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

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 PartialOrd for Level

fn partial_cmp(&self, other: &Level) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub<u8> for Level

type Output = Level

The resulting type after applying the - operator.

fn sub(self, value: u8) -> Self

Performs the - operation.

impl TryFrom<usize> for Level

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(sz: usize) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Level

impl Eq for Level

impl StructuralPartialEq for Level
