Struct ide_db::famous_defs::FamousDefs

pub struct FamousDefs<'a, 'b>(pub &'a Semantics<'b, RootDatabase>, pub Crate);

Helps with finding well-know things inside the standard library. This is somewhat similar to the known paths infra inside hir, but it different; We want to make sure that IDE specific paths don’t become interesting inside the compiler itself as well.

Note that, by default, rust-analyzer tests do not include core or std libraries. If you are writing tests for functionality using FamousDefs, you’d want to include minicore (see test_utils::MiniCore) declaration at the start of your tests:

//- minicore: iterator, ord, derive

Tuple Fields

0: &'a Semantics<'b, RootDatabase>
