Struct scrypto::math::U256

source ·
#[repr(transparent)]
pub struct U256(pub BUint<4>);
Expand description

Provides safe integer arithmetic.

Operations like +, ‘-’, ‘*’, or ‘/’ sometimes produce overflow which is detected and results in a panic, in of silently wrapping around.

The bit length of output type will be the greater one in the math operation, and if any of the types was signed, then the resulting type will be signed too, otherwise the output type is unsigned.

The underlying value can be retrieved through the .0 index of the U256 tuple.

§Layout

U256 will have the same methods and traits as the built-in counterpart.

Implementations§

source§

impl U256

source

pub const fn count_ones(self) -> u32

Returns the number of ones in the binary representation of self.

source

pub const fn count_zeros(self) -> u32

Returns the number of zeros in the binary representation of self.

source

pub const fn trailing_zeros(self) -> u32

Returns the number of trailing zeros in the binary representation of self.

source

pub const fn swap_bytes(self) -> U256

Reverses the byte order of the integer.

source

pub const fn reverse_bits(self) -> U256

Reverses the bit pattern of the integer.

source

pub const fn leading_zeros(self) -> u32

Returns the number of leading zeros in the binary representation of self.

source

pub const fn from_be(x: U256) -> U256

Converts an integer from big endian to the target’s endianness.

On big endian this is a no-op. On little endian the bytes are swapped.

source

pub const fn from_le(x: U256) -> U256

Converts an integer from little endian to the target’s endianness.

On little endian this is a no-op. On big endian the bytes are swapped.

source

pub const fn to_be(self) -> U256

Converts self to big endian from the target’s endianness.

On big endian this is a no-op. On little endian the bytes are swapped.

source

pub const fn to_le(self) -> U256

Converts self to little endian from the target’s endianness.

On little endian this is a no-op. On big endian the bytes are swapped.
