// We represent a slice as a pair of an (untyped) pointer, along with the length
// of the slice, i.e. the number of elements in the slice (this is NOT the
// number of bytes). This design choice has two important consequences.
// - if you need to use `ptr`, you MUST cast it to a proper type *before*
// performing pointer
//   arithmetic on it (remember that C desugars pointer arithmetic based on the
//   type of the address)
// - if you need to use `len` for a C style function (e.g. memcpy, memcmp), you
// need to multiply it
//   by sizeof t, where t is the type of the elements.
//
// Empty slices have `len == 0` and `ptr` always needs to be valid pointer that
// is not NULL (otherwise the construction in EURYDICE_SLICE computes `NULL +
// start`).

 Only a multiple of `RATE` blocks are absorbed.

 This works best with relatively small `inputs`.

/**
 Compute the product of two Kyber binomials with respect to the
 modulus `X² - zeta`.

 This function almost implements <strong>Algorithm 11</strong> of the
 NIST FIPS 203 standard, which is reproduced below:

 ```plaintext
 Input:  a₀, a₁, b₀, b₁ ∈ ℤq.
 Input: γ ∈ ℤq.
 Output: c₀, c₁ ∈ ℤq.

 c₀ ← a₀·b₀ + a₁·b₁·γ
 c₁ ← a₀·b₁ + a₁·b₀
 return c₀, c₁
 ```
 We say "almost" because the coefficients output by this function are in
 the Montgomery domain (unlike in the specification).

 Given two `KyberPolynomialRingElement`s in their NTT representations,
 compute their product. Given two polynomials in the NTT domain `f^` and `ĵ`,
 the `iᵗʰ` coefficient of the product `k̂` is determined by the calculation:

 ```plaintext
 ĥ[2·i] + ĥ[2·i + 1]X = (f^[2·i] + f^[2·i + 1]X)·(ĝ[2·i] + ĝ[2·i + 1]X) mod (X²
 - ζ^(2·BitRev₇(i) + 1))
 ```

 This function almost implements <strong>Algorithm 10</strong> of the
 NIST FIPS 203 standard, which is reproduced below:

 ```plaintext
 Input: Two arrays fˆ ∈ ℤ₂₅₆ and ĝ ∈ ℤ₂₅₆.
 Output: An array ĥ ∈ ℤq.

 for(i ← 0; i < 128; i++)
     (ĥ[2i], ĥ[2i+1]) ← BaseCaseMultiply(fˆ[2i], fˆ[2i+1], ĝ[2i], ĝ[2i+1],
 ζ^(2·BitRev₇(i) + 1)) end for return ĥ
 ```
 We say "almost" because the coefficients of the ring element output by
 this function are in the Montgomery domain.

 <https://csrc.nist.gov/pubs/fips/203/ipd>.

/**
 If `bytes` contains a set of uniformly random bytes, this function
 uniformly samples a ring element `â` that is treated as being the NTT
 representation of the corresponding polynomial `a`.

 Since rejection sampling is used, it is possible the supplied bytes are
 not enough to sample the element, in which case an `Err` is returned and the
 caller must try again with a fresh set of bytes.

 This function <strong>partially</strong> implements <strong>Algorithm
 6</strong> of the NIST FIPS 203 standard, We say "partially" because this
 implementation only accepts a finite set of bytes as input and returns an error
 if the set is not enough; Algorithm 6 of the FIPS 203 standard on the other
 hand samples from an infinite stream of bytes until the ring element is filled.
 Algorithm 6 is reproduced below:

/**
 Given a series of uniformly random bytes in `randomness`, for some number
 `eta`, the `sample_from_binomial_distribution_{eta}` functions sample a ring
 element from a binomial distribution centered at 0 that uses two sets of `eta`
 coin flips. If, for example, `eta = ETA`, each ring coefficient is a value `v`
 such such that `v ∈ {-ETA, -ETA + 1, ..., 0, ..., ETA + 1, ETA}` and:

 ```plaintext
 - If v < 0, Pr[v] = Pr[-v]
 - If v >= 0, Pr[v] = BINOMIAL_COEFFICIENT(2 * ETA; ETA - v) / 2 ^ (2 * ETA)
 ```

 The values `v < 0` are mapped to the appropriate `KyberFieldElement`.

 The expected value is:

 ```plaintext
 E[X] = (-ETA)Pr[-ETA] + (-(ETA - 1))Pr[-(ETA - 1)] + ... + (ETA - 1)Pr[ETA - 1]
 + (ETA)Pr[ETA] = 0 since Pr[-v] = Pr[v] when v < 0.
 ```

 And the variance is:

 ```plaintext
 Var(X) = E[(X - E[X])^2]
        = E[X^2]
        = sum_(v=-ETA to ETA)v^2 * (BINOMIAL_COEFFICIENT(2 * ETA; ETA - v) /
 2^(2 * ETA)) = ETA / 2
 ```

 This function implements <strong>Algorithm 7</strong> of the NIST FIPS 203
 standard, which is reproduced below:

 ```plaintext
 Input: byte array B ∈ ��^{64η}.
 Output: array f ∈ ℤ₂₅₆.

 b ← BytesToBits(B)
 for (i ← 0; i < 256; i++)
     x ← ∑(j=0 to η - 1) b[2iη + j]
     y ← ∑(j=0 to η - 1) b[2iη + η + j]
     f[i] ← x−y mod q
 end for
 return f
 ```
