Struct RandomManager 

pub struct RandomManager {
    sources: Mutex<Vec<Arc<dyn EntropySource>>>,
    pool: Mutex<VecDeque<u8>>,
}

Random number generator manager

This is the central component that manages entropy sources and provides random numbers to the rest of the kernel.

Fields

sources: Mutex<Vec<Arc<dyn EntropySource>>>

Registered entropy sources

pool: Mutex<VecDeque<u8>>

Internal random pool buffer

Implementations

impl RandomManager

fn new() -> Self

Create a new RandomManager

fn instance() -> &'static RandomManager

Get the global RandomManager instance

pub fn register_entropy_source(source: Arc<dyn EntropySource>)

Register an entropy source

Arguments

• source - The entropy source to register

fn fill_pool(&self) -> Result<usize, &'static str>

Fill the internal pool with entropy from available sources

pub fn get_random_bytes(buffer: &mut [u8]) -> usize

Get random bytes from the pool

Arguments

• buffer - Buffer to fill with random data

Returns

Number of bytes actually written

pub fn get_random_byte() -> Option<u8>

Read a single random byte
