Struct format_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.

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for U128<E>

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> FromByteSlice for U128<E>

fn from_byte_slice(s: &[u8]) -> Result<&Self, InvalidSizeError>

Transmutes an immutable byte slice reference into an immutable Self reference.

fn from_byte_slice_mut(s: &mut [u8]) -> Result<&mut Self, InvalidSizeError>

Transmutes a mutable byte slice reference into a mutable Self reference.

fn slice_from_byte_slice(s: &[u8]) -> Result<&[Self], InvalidSizeError>

Transmutes an immutable byte slice reference into an immutable to a slice of Self.

fn slice_from_byte_slice_mut( s: &mut [u8] ) -> Result<&mut [Self], InvalidSizeError>

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
