Struct scrypto::math::U256

#[repr(transparent)]
pub struct U256(pub BUint<4>);

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.
