Only `NonZero`/`NonMax` aliases if those features have been enabled

Fixes

• Only define NonZero and NonMax aliases if those features have been enabled (qwnmsrvm)
  • Fixes compilation errors present in v0.1.6
• Only run nonzero/nonmax tests if those features are enabled (pxvwytsn)
• Fix use of BuildHasher::hash_one breaking doctests before 1.71 (rpnulmvl)

Guarantee NonZero, NonMax have same Ord, Hash as underlying type

Make Hash impl for NonMax satisfy this property.
All other trait implementations already satisfied this.

Changed

• Officially guarantee that NonMax<T> and NonZero<T> implement Hash the same as T (zoxoyvnx)
• Similarly guarantee that NonMax<T> and NonZero<T> implement Ord the same as T (lzlwsrtp)
  • This has always been the case for both types.

Fixes

• The Hash impl for NonMax now behaves the same as the underlying type T. (ppmqkvzx)
  • This property has always been true of NonZero, but has not been true for NonMax

Implement From impls for NonZero, NonMax

Added

• Add type aliases for NonMax and NonZero (i.e. NonZeroU32, NonMaxU32, etc.) (unqpkqks)
• Add infallible From conversions for NonMax, NonZero (xutqswvn)
  • No failable conversions yet, as that would require defining a TryFromIntError type.
• Add BITS associated constant to NonMax, NonZero (rslwssvw)
• Add ONE, ZERO constants to NonMax and ONE constant to NonZero (mkyykwvx)
• Require PrimitiveInt to implement int format traits (Binary, LowerHex, etc.) (kkmsmlmr)
  • This was always true of the underlying integer types, but not required by the trait.
• Implement int format traits for NonZero, NonMax (Binary, LowerHex, etc.) (mrlslmyw)
  • Always implemented by delegating to underlying type, just like stdlib and the nonmax crate.

Changes

• Delegate Debug impl for NonZero, NonMax to underlying type (qnlmtkkx)
  • Makes behavior consistent with stdlib and nonmax crate.
  • Previous behavior for NonZero was to format as newtype tuple struct (0 formats as NonZero(0)]
  • Previous behavior for NonMax was excessively verbose and exposed internal implementation details.
  • I don't consider this breaking since previous behavior was not guaranteed.
    The new behavior is guaranteed unless the stdlib changes it behavior.

Fixes

• Fix Default impl for NonMax to return zero instead of one.

Make NonZero::new, NonMax::{new, get} a const fn

Added

• Implement Display for NonZero, NonMax (svrxxntk)
• Implement BitOr for NonZero, BitAnd for NonMax (rrlpzwum)

Changed

• Mark NonZero::new, NonMax::{new, new_unchecked, get} as const fn (vnvwkvzp)

Hide NonZero, NonMax behind on-by-default features.

Added

• Implement Default for NonMax (wmvtkkqk)

Changed

• Hide NonZero, NonMax behind on-by-default feature flags (nktrlykq)
• Reduce MSRV from 1.71 back to 1.64 (rupzyqzu)

Fixed

• Restore compatibility with rust versions before 1.83 by avoiding const_refs_to_cell feature i(ssue #1) (nktrlykq)

Add NonZero and NonMax types, generic over PrimitiveInt

Added

• Add wrapping_add and wrapping_sub functions (wznskrrp)
• Add NonZero struct to mirror core::num::NonZero, but made generic over PrimitiveInt (xooqvysu)
• Add NonMax struct to mirror the NonZero struct (msuozwwt)
  • Offers alternative to the nonmax crate.
  • Implemented in terms of NonZero type as stdlib doesn't offer it natively.

Changed

• Bump MSRV to 1.71

Add FromStr bound to PrimitiveInt

Added

• Add core::str::FromStr bound to PrimitiveInt (xwvtvksx)

Fixed

• Remove dead link to nonexistent PrimitiveInteger in crate docs (xxxzxqpn)
  The real trait name is actually PrimitiveInt.

Initial release

Includes all functionality needed by the intid.rs project.
