Struct Stem 

pub struct Stem(pub [u8; 31]);

A 31-byte stem that identifies a subtree of 256 values.

Tuple Fields

0: [u8; 31]

Implementations

impl Stem

pub const fn new(bytes: [u8; 31]) -> Self

Create a new stem from bytes.

pub fn from_slice(slice: &[u8]) -> Self

Create a stem from a slice. Panics if length != 31.

pub const fn as_bytes(&self) -> &[u8; 31]

Get the underlying bytes.

pub fn is_zero(&self) -> bool

Check if this stem is all zeros.

pub fn bit_at(&self, pos: usize) -> bool

Get bit at position (0 = MSB of first byte, 247 = LSB of last byte). This is used for tree traversal.

pub fn first_differing_bit(&self, other: &Self) -> Option<usize>

Find the first bit position where two stems differ. Returns None if stems are equal.

Trait Implementations

impl Clone for Stem

fn clone(&self) -> Stem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stem

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

Formats the value using the given formatter.

impl Default for Stem

fn default() -> Stem

Returns the “default value” for a type.

impl From<[u8; 31]> for Stem

fn from(bytes: [u8; 31]) -> Self

Converts to this type from the input type.

impl Hash for Stem

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 Stem

fn cmp(&self, other: &Self) -> 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 Stem

fn eq(&self, other: &Stem) -> 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 Stem

fn partial_cmp(&self, other: &Self) -> 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.
