Split the field arithmetic implementations into `FieldElement`, `FieldElement32`, and `FieldElement64`. `FieldElement` is a type alias for one of `FieldElement32` or `FieldElement64`, depending on feature selection. `field.rs` contains tests and code which is generic with respect to the implementation (e.g., inversions), while `field_32bit.rs` and `field_64bit.rs` contain the implementation-specific code. The implementation is not completely hidden, since `FieldElement32` and `FieldElement64` are tuple structs whose elements are public; `pub(crate)` doesn't seem to work for tuple structs. Similarly, the constants file is split over multiple files, depending on the implementation.

//! # curve25519-dalek
|
|
//!
|
|
//! **A Rust implementation of field and group operations on an Edwards curve
|
|
//! over GF(2^255 - 19).**
|
|
//!
|
|
//! **[SPOILER ALERT]** The Twelfth Doctor's first encounter with the Daleks is
|
|
//! in his second full episode, "Into the Dalek". A beleaguered ship of the
|
|
//! "Combined Galactic Resistance" has discovered a broken Dalek that has
|
|
//! turned "good", desiring to kill all other Daleks. The Doctor, Clara and a
|
|
//! team of soldiers are miniaturized and enter the Dalek, which the Doctor
|
|
//! names Rusty. They repair the damage, but accidentally restore it to its
|
|
//! original nature, causing it to go on the rampage and alert the Dalek fleet
|
|
//! to the whereabouts of the rebel ship. However, the Doctor manages to
|
|
//! return Rusty to its previous state by linking his mind with the Dalek's:
|
|
//! Rusty shares the Doctor's view of the universe's beauty, but also his deep
|
|
//! hatred of the Daleks. Rusty destroys the other Daleks and departs the
|
|
//! ship, determined to track down and bring an end to the Dalek race.
