How deeply does Idiomatic Rust cover contiguous memory layout?

Explains cache locality, compiler optimization opportunities, and element shifting, while noting that alternatives can win some workloads.

Contiguous memory layout

As explained in Idiomatic Rust

Contiguous memory is a region whose elements occupy adjacent memory addresses.

Contiguous memory places elements in adjacent addresses. Rust’s Vec benefits from this layout: nearby data is cache-friendly, and moving elements can often be handled with fast memory copying. section 10.4

These advantages make Vec a strong default for many workloads, but not a universal winner. Some sets, maps, trees, or linked lists can outperform it; benchmark before choosing a more complex structure. section 10.4

Compare collection performance

Benchmark Vec, HashSet, and LinkedList for appending, searching, and removing elements to see how their performance differs across operations. section 10.4
