399: Make getters and setters have the visibility of their field r=nikomatsakis a=MihailMihov resolves #398 Currently `#[salsa::input]` and `#[salsa::tracked]` structs made all getters and setters public, regardless of the visibility of the field and the getters for `#[salsa::interned]` had the visibility of the struct itself. This pull request changes the generated impl's to use the visibility of each field for it's getters and setters. Co-authored-by: Mihail Mihov <mmihov.personal@gmail.com> |

salsa
A generic framework for on-demand, incrementalized computation.
Obligatory warning
Very much a WORK IN PROGRESS at this point. Ready for experimental use but expect frequent breaking changes.
Credits
This system is heavily inspired by adapton, glimmer, and rustc's query system. So credit goes to Eduard-Mihai Burtescu, Matthew Hammer, Yehuda Katz, and Michael Woerister.
Key idea
The key idea of salsa is that you define your program as a set of
queries. Every query is used like function K -> V that maps from
some key of type K to a value of type V. Queries come in two basic
varieties:
- Inputs: the base inputs to your system. You can change these whenever you like.
- Functions: pure functions (no side effects) that transform your inputs into other values. The results of queries are memoized to avoid recomputing them a lot. When you make changes to the inputs, we'll figure out (fairly intelligently) when we can re-use these memoized values and when we have to recompute them.
