Struct GenerationToken 

pub struct GenerationToken { /* private fields */ }

An opaque generation token binding an index snapshot generation and a 128-bit CSPRNG process nonce into a single opaque string.

Per the spec: equality is the only permitted operation. Substring, split, parse, order, and range comparisons are strictly forbidden.

Implementations

impl GenerationToken

pub fn new(snapshot_generation: u64) -> Self

Construct a new opaque generation token from an index snapshot generation u64 and the process-wide 128-bit CSPRNG process nonce.

pub fn new_with_str(snapshot_generation: &str) -> Self

Construct a new opaque generation token from an index snapshot generation string and the process-wide 128-bit CSPRNG process nonce.

pub fn new_with_nonce(snapshot_generation: &str, nonce: [u8; 16]) -> Self

Construct a token with an explicit 128-bit nonce (useful for deterministic fixtures and testing).

pub fn as_str(&self) -> &str

Return the opaque token as a string slice for serialization and display.
