chore: Update Rust version (#1445)

* chore: Update Rust version

* refactor: Make struct constructor field orderings consistent

Sometimes I changed the struct definition, sometimes changed the struct
construction instance, depending on consistency with code around each
(other similar structs, function argument orders, etc)

More info: https://rust-lang.github.io/rust-clippy/master/index.html#inconsistent_struct_constructor

* refactor: Use flatten where appropriate

One instance is a false positive with a clippy bug.

More info:

- https://rust-lang.github.io/rust-clippy/master/index.html#filter_map_identity
- https://rust-lang.github.io/rust-clippy/master/index.html#manual_flatten

* refactor: Use Option map instead of match

More info: https://rust-lang.github.io/rust-clippy/master/index.html#manual_map
