Struct ClassicalMcElieceRng 

pub struct ClassicalMcElieceRng { /* private fields */ }

Classical McEliece compatible RNG

This RNG provides the same interface as the original AesState but uses libQ’s standard RNG infrastructure instead of AES-based generation.

Implementations

impl ClassicalMcElieceRng

pub fn new() -> Self

Create a new secure RNG using system entropy

Random output is drawn with getrandom::fill. The classical-mceliece crate feature enables the getrandom dependency so non-test builds always have OS entropy available (including wasm_js on wasm32-unknown-unknown when configured in the dependency graph).

pub fn new_deterministic(seed: u64) -> Self

Create a new deterministic RNG for testing

This creates an RNG that produces deterministic output based on the seed. This is useful for testing and reproducible key generation.

pub fn new_deterministic_from_bytes(seed_bytes: &[u8]) -> Self

Create a new deterministic RNG from byte array

This creates an RNG that produces deterministic output based on the byte array. The bytes are hashed to create a 64-bit seed.

pub fn randombytes_init(&mut self, entropy_input: [u8; 48])

Initialize the RNG with entropy (for deterministic mode)

This method is provided for compatibility with the original AesState interface. In deterministic mode, it updates the internal state. In secure mode, it’s a no-op as the RNG uses system entropy.

Trait Implementations

impl Clone for ClassicalMcElieceRng

fn clone(&self) -> ClassicalMcElieceRng

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClassicalMcElieceRng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ClassicalMcElieceRng

fn default() -> Self

Returns the “default value” for a type.

impl Display for ClassicalMcElieceRng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ClassicalMcElieceRng

fn eq(&self, other: &ClassicalMcElieceRng) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryRng for ClassicalMcElieceRng

type Error = Infallible

The type returned in the event of a RNG error.

fn try_next_u32(&mut self) -> Result<u32, Self::Error>

Return the next random u32.

fn try_next_u64(&mut self) -> Result<u64, Self::Error>

Return the next random u64.

fn try_fill_bytes(&mut self, dest: &mut [u8]) -> Result<(), Self::Error>

Fill dst entirely with random data.
