Dana Jansens 4cf2c07f7d Explain more on the difference of where constraints (#4551)
This adds language to explain where the types of constraints can or can
not appear (attached-to an impl-as vs in-a type expression). And
describes the impact of using a rewrite vs same-type constraint inside
the body of the affected code, and thus why a rewrite is preferable when
the constraint is of a single facet type.

Generics

This directory contains the collection of documents describing the generics feature of Carbon:

  • Overview - A high-level description of the generics design, with pointers to other design documents that dive deeper into individual topics
  • Goals - The motivation and principles guiding the design direction
  • Terminology - A glossary establishing common terminology for describing the design
  • Detailed design - In-depth description
    • Appendix: Coherence - Describes the rationale for Carbon's choice to have coherent generics, and the alternatives.
    • Appendix: Rewrite constraints - Describes the detailed rules governing rewrite constraints, and why resolving them terminates.
    • Appendix: Witness tables - Describes an implementation strategy for checked generics, and Carbon's rationale for only using it for dynamic dispatch.
