Add constants Zero::ZERO and One::ONE #298

Closed Sympatron closed 11 months ago

Sympatron commented 11 months ago

Currently all trait methods are not usable in const contexts. Since zero is also the default value of all number types, this can be useful as a replacement for Default::default() in const contexts.

PS: Is there a reason that none of the traits provide constant versions of their values?

It's a breaking change, and allocated types like bigint can't support this. See also #276.
