Tests that specialization is working correctly:
|
||
|
|
|
||
|
|
- Dispatch
|
||
|
|
- [On methods](specialization-basics.rs), includes:
|
||
|
|
- Specialization via adding a trait bound
|
||
|
|
- Including both remote and local traits
|
||
|
|
- Specialization via pure structure (e.g. `(T, U)` vs `(T, T)`)
|
||
|
|
- Specialization via concrete types vs unknown types
|
||
|
|
- In top level of the trait reference
|
||
|
|
- Embedded within another type (`Vec<T>` vs `Vec<i32>`)
|
||
|
|
- [Specialization based on super trait relationships](specialization-supertraits.rs)
|
||
|
|
- [On assoc fns](specialization-assoc-fns.rs)
|
||
|
|
- [Ensure that impl order doesn't matter](specialization-out-of-order.rs)
|
||
|
|
|
||
|
|
- Item inheritance
|
||
|
|
- [Correct default cascading for methods](specialization-default-methods.rs)
|
||
|
|
- Inheritance works across impls with varying generics
|
||
|
|
- [With projections](specialization-translate-projections.rs)
|
||
|
|
- [With projections that involve input types](specialization-translate-projections-with-params.rs)
|
||
|
|
|
||
|
|
- Normalization issues
|
||
|
|
- [Non-default assoc types can be projected](specialization-projection.rs)
|
||
|
|
- Including non-specialized cases
|
||
|
|
- Including specialized cases
|
||
|
|
- [Specialized Impls can happen on projections](specialization-on-projection.rs)
|
||
|
|
- [Projections and aliases play well together](specialization-projection-alias.rs)
|
||
|
|
- [Projections involving specialization allowed in the trait ref for impls, and overlap can still be determined](specialization-overlap-projection.rs)
|
||
|
|
- Only works for the simple case where the most specialized impl directly
|
||
|
|
provides a non-`default` associated type
|
||
|
|
|
||
|
|
- Across crates
|
||
|
|
- [For traits defined in upstream crate](specialization-allowed-cross-crate.rs)
|
||
|
|
- [Full method dispatch tests, drawing from upstream crate](specialization-cross-crate.rs)
|
||
|
|
- Including *additional* local specializations
|
||
|
|
- [Full method dispatch tests, *without* turning on specialization in local crate](specialization-cross-crate-no-gate.rs)
|
||
|
|
- [Test that defaults cascade correctly from upstream crates](specialization-cross-crate-defaults.rs)
|
||
|
|
- Including *additional* local use of defaults
