}

| 256-bit opaque blob. | | ———– | @note | | This type is called uint256 for historical | reasons only. It is an opaque blob of | 256 bits and has no integer operations. | Use arith_uint256 if those are required. |

Trait Implementations

impl Clone for u256

fn clone(&self) -> u256

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for u256

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

Formats the value using the given formatter.

impl Default for u256

fn default() -> u256

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for u256

fn deserialize<D>(_deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&String> for u256

| uint256 from std::string. | | This is a separate function because | the constructor uint256(const std::string | &str) can result in dangerously catching | uint256(0) via std::string(const | char*). |

fn from(str_: &String) -> Self

Converts to this type from the input type.

impl From<&Vec<u8, Global>> for u256

fn from(v: &Vec<u8>) -> Self

Converts to this type from the input type.

impl From<*const u8> for u256

| uint256 from const char . | | This is a separate function because | the constructor uint256(const char) | can result in dangerously catching | uint256(0). |

fn from(str_: *const u8) -> Self

Converts to this type from the input type.

impl From<u8> for u256

fn from(v: u8) -> Self

Converts to this type from the input type.

impl Hash for u256

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 u256

fn cmp(&self, other: &u256) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<u256> for u256

fn eq(&self, other: &u256) -> 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.

impl PartialOrd<u256> for u256

fn partial_cmp(&self, other: &u256) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for u256

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
