In Rust this is an anti-pattern: indexed access can be slower (as it needs to
be bounds checked) and may prevent various compiler optimisations.
It is important to see this distinction in Rust vs C, as Rust needs to check for out-of-bounds access when manually indexing an array to guarantee memory safety, while C will happily index outside the array if given an index that will do so.
