Struct U128 

pub struct U128<const VAL: u128>;

Marker type for passing const VAL: u128 as a type parameter.

Serde compatibility

When the "serde" feature is enabled, this type is serialized/deserialized as the VAL const parameter.

use typewit::const_marker::U128; 
 
assert_eq!(serde_json::from_str::<U128<1>>("1").unwrap(), U128::<1>); 
 
// trying to deserialize `U128<1>` from any value other than `1` produces an error 
assert!(serde_json::from_str::<U128<1>>("0").is_err()); 
 
 
assert_eq!(serde_json::to_string(&U128::<1>).unwrap(), "1"); 
 
assert_eq!(serde_json::to_string(&U128::<92>).unwrap(), "92"); 
 

Implementations

impl<const VAL: u128> U128<VAL>

pub const fn eq<const OTHER: u128>( self, _other: U128<OTHER>, ) -> Result<TypeEq<U128<VAL>, U128<OTHER>>, TypeNe<U128<VAL>, U128<OTHER>>>

👎Deprecated since 1.8.0:

superceeded by equals method

Compares self and other for equality.

Returns:

• Ok(TypeEq): if VAL == OTHER
• Err(TypeNe): if VAL != OTHER

pub const fn equals<const OTHER: u128>( self, _other: U128<OTHER>, ) -> TypeCmp<U128<VAL>, U128<OTHER>>

Compares self and other for equality.

Returns:

• TypeCmp::Eq(TypeEq): if VAL == OTHER
• TypeCmp::Ne(TypeNe): if VAL != OTHER

Trait Implementations

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

The value of this constant

type Of = u128

The type of this constant

impl<const VAL: u128> Debug for U128<VAL>

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

Formats the value using the given formatter.

impl<const VAL: u128> Default for U128<VAL>

fn default() -> Self

Returns the “default value” for a type.

impl<const VAL: u128> Hash for U128<VAL>

fn hash<H>(&self, state: &mut H)

where H: Hasher,

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<const VAL: u128> Ord for U128<VAL>

fn cmp(&self, _: &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<const L: u128, const R: u128> PartialEq<U128<R>> for U128<L>

fn eq(&self, _: &U128<R>) -> 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<const L: u128, const R: u128> PartialOrd<U128<R>> for U128<L>

fn partial_cmp(&self, _: &U128<R>) -> 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.
