Tracking issue for Range*::contains

[alexcrichton]

Tracking issue for rust-lang/rfcs#1434.

Unresolved questions:

• What to do about Wrapping ranges.

Implementation work:

• Heterogeneous comparisons
• Should take a reference

I am unsure what part of the rfc was accepted. Is the contains method for iterators accepted?

[alexcrichton]

The accepted portion of an RFC is the detailed design, which in this case only deals with ranges, not iterators.

[ticki]

Well, okay. Fine.

[ticki]

It is in fact also compatible with future extension to iterators.

[durka]

Should this be implemented for (unstable) RangeInclusive and RangeToInclusive as well?

[alexcrichton]

For consistency, yeah, seems prudent.

[Kimundi]

Hm, I just used this and expected it to take &Idx instead of Idx, in case you have a range of non-copyable types.

Looking back the RFC, it does not seem to consider this case - was there any discussion for this possibility?
