Implement RFC 873: Type Macros #27296
Conversation

r? @huonw (rust_highfive has picked a reviewer for you, use r? to override) |
|
Can you ad a feature gate (standard procedure)? |
|
@nikomatsakis yeah, I wasn't clear about how we were doing RFCs. Feature gate for one release cycle? |
| ("default_type_parameter_fallback", "1.3.0", Active), | ||
|
|
||
| // Allows macros to appear in the type position. | ||
| ("type_macros", "1.3.0", Active) |
|
Could you add a compile-fail test for the feature gate? And maybe some more basic run-pass tests for the macros themselves? |

☔ The latest upstream changes (presumably #27382) made this pull request unmergeable. Please resolve the merge conflicts. |

There was a problem hiding this comment.
I think (see issue #27336) is a slightly better phrasing of this.

r=me with an ERROR in the compile-fail test (and some nits). |

This pull request implements the functionality for [RFC 873](https://github.com/rust-lang/rfcs/blob/master/text/0873-type-macros.md). This is currently just an update of @freebroccolo's branch from January, the corresponding commits are linked in each commit message. @nikomatsakis and I had talked about updating the macro language to support a lifetime fragment specifier, and it is possible to do that work on this branch as well. If so we can (collectively) talk about it next week during the pre-RustCamp work week.
