Struct RandomIds 

pub struct RandomIds { /* private fields */ }

Mints session identities from the operating system’s CSPRNG.

Cheap to construct, Sync, and safe to share: IdSource::next_session_id takes &self, so one instance serves every session a server opens.

Examples

use protocol_droid::adapters::secondary::id_source::RandomIds;
use protocol_droid::application::session::IdSource;

let ids = RandomIds::new()?;
let first = ids.next_session_id();
let second = ids.next_session_id();
assert_ne!(first, second);

Implementations

impl RandomIds

pub fn new() -> Result<Self, EntropyError>

Seed a source from the operating system.

Errors

Returns EntropyError::Unavailable if the platform entropy source cannot be read. Constructing from a hardcoded seed would make this type a counter with extra steps, so the failure is reported rather than papered over.

Trait Implementations

impl Debug for RandomIds

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

Formats the value using the given formatter.

impl IdSource for RandomIds

fn next_session_id(&self) -> SessionId

A fresh identity.
