The Swift ABI defines an interesting [struct layout](https://github.com/apple/swift/blob/master/docs/ABI.rst#fragile-struct-and-tuple-layout) which defines the size of a type separately from its stride: > Note that this differs from C or LLVM's normal layout...
```rust #[derive(Debug, Clone, PartialEq, Eq)] pub struct NotFound { pub index: Idx } pub trait TryIndex { type Output; fn try_index(&self, index: Idx) -> Result; } pub trait TryIndexMut {...
## Background Numerical types with defined constraints can be a useful way to perform some sanity checks at compile time. Ada is one of language I know which has these...
The idea of a `!=` constraint form in `where` clauses has come up multiple times, in discussions of the `where` clause itself, in https://github.com/rust-lang/rust/issues/20041 as a counterpart to the `==`...
Hi, As suggested in an old and closed but still active [discussion](https://github.com/rust-lang/rfcs/issues/920), I open another thread because it looks interesting to have the capability to have inline comments. My use...
