Implement IntoPropValue for Rc<str>

[zstewar1]

Description

Add impl_into_prop! for Rc<str>.

AttrValue already has a variant for Rc<str>, but it's not currently possible to use that in Yew virtual DOM, because that requires IntoPropValue<Option<AttrValue>> which isn't implemented. This change adds a set of those implementations using the existing macro.

Checklist

• I have run cargo make pr-flow
• I have reviewed my own code
• I have added tests
  • If this is a feature, my tests prove that the feature works: yes, at least as well as the existing tests prove it works for String and &'static str.

Looks good. I'll approve it once CI is green. I have no idea why it's failing though. You can try merging master into your branch. If that doesn't do it, try running cargo update -p trybuild and then run cargo make tests-overwrite in yew-macro directory. You'll need cargo-make and Rust 1.51 installed for this.

There's a test checking that certain builds fail as expected, and it does a comparison of the exact expected log output. A couple of those lines include listing the number of impls of a certain type, and this PR adds 3 more impls. I'll re-run with the suggested command to bless the new logs later.
