pub struct Scalar(pub [u32; 8]);
Expand description

A 256-bit scalar value.

Tuple Fields

0: [u32; 8]

Implementations

Clear a scalar to prevent the leak of sensitive data.

Check whether a scalar equals zero.

Check whether a scalar equals one.

Check whether a scalar is higher than the group order divided by 2.

Conditionally negate a number, in constant time.

Shift a scalar right by some amount strictly between 0 and 16, returning the low bits that were shifted off.
