Struct U64 

#[repr(C)]
pub struct U64<E>(/* private fields */);

A type that wraps a byte array to be decoded into a u64.

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> U64<E>

pub const fn from_bytes(bytes: [u8; 8]) -> Self

Converts a byte array into a U64.

pub const fn into_bytes(self) -> [u8; 8]

impl U64<Endian>

pub const fn new_with_endian(value: u64, endian: Endian) -> Self

Constructs a U64 wrapper type from a u64 value using the specified endianness.

pub const fn get_with_endian(self, endian: Endian) -> u64

pub const fn get(self) -> u64

Extracts a u64 value from a U64 wrapper using the type’s fixed endianness.

Trait Implementations

impl<E: Clone> Clone for U64<E>

impl<E> Default for U64<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: FixedEndian> From<u64> for U64<E>

fn from(value: u64) -> Self

Converts to this type from the input type.

impl<E: Hash> Hash for U64<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)

impl<E: PartialEq> PartialEq for U64<E>

fn eq(&self, other: &U64<E>) -> bool
