Struct U128

#[repr(C)]
pub struct U128<E>(/* private fields */);

A type that wraps a byte array to be decoded into a u128.

The generic parameter represents the endianness used to decode the wrapped value. In case the value is expected to have fixed endianness, either BigEndian or LittleEndian types should be used, otherwise the Endian type.

Implementations

impl<E> U128<E>

pub const fn from_bytes(bytes: [u8; 16]) -> Self

Converts a byte array into a U128.

pub const fn into_bytes(self) -> [u8; 16]

Converts a U128 into a byte array.

impl U128<Endian>

pub const fn new_with_endian(value: u128, endian: Endian) -> Self

Constructs a U128 wrapper type from a u128 value using the specified endianness.

pub const fn get_with_endian(self, endian: Endian) -> u128

impl<E: FixedEndian> U128<E>

pub const fn new(value: u128) -> Self

pub const fn get(self) -> u128

Extracts a u128 value from a U128 wrapper using the type’s fixed endianness.

Trait Implementations

impl<E: Clone> Clone for U128<E>

fn clone(&self) -> U128<E>

Returns a duplicate of the value.

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

Formats the value using the given formatter.

impl Debug for U128<Endian>

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

Formats the value using the given formatter.

impl Debug for U128<LittleEndian>

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

Formats the value using the given formatter.

impl<E> Default for U128<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: FixedEndian> From<u128> for U128<E>

fn from(value: u128) -> Self

Converts to this type from the input type.

impl<E: Hash> Hash for U128<E>

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<E: PartialEq> PartialEq for U128<E>

fn eq(&self, other: &U128<E>) -> 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.
