Basic Rust naming conventions are described in [RFC 430].

In general, Rust tends to use `CamelCase` for "type-level" constructs (types and
In general, Rust tends to use `PascalCase` for "type-level" constructs (types and
traits) and `snake_case` for "value-level" constructs. More precisely:

In `CamelCase`, acronyms and contractions of compound words count as one word: use `Uuid` rather than `UUID`, `Usize` rather than `USize` or `Stdin` rather than `StdIn`. In `snake_case`, acronyms and contractions are lower-cased: `is_xid_start`.

In `snake_case` or `SCREAMING_SNAKE_CASE`, a "word" should never consist of a
single letter unless it is the last "word". So, we have `btree_map` rather than
