Struct ReplayDefenseState 

pub struct ReplayDefenseState {
    pub domain: String,
    pub signature: Option<String>,
    pub nonce: Option<String>,
    pub captured_at_epoch_ms: u64,
}

Per-session replay-defense state captured when the session was first bound.

The state is the frozen record the runner compares against the freshly observed context on every reuse. It is fully serialisable so the existing session snapshot path (SessionSnapshot in Browser T23) can persist and reload it across restarts.

Example

use stygian_browser::replay_defense::ReplayDefenseState;

let captured = stygian_browser::freshness::unix_epoch_ms();
let state = ReplayDefenseState::with_fingerprint(
    "example.com",
    "sha256:abc",
    Some("nonce-001"),
    captured,
);
assert_eq!(state.domain, "example.com");
assert_eq!(state.signature.as_deref(), Some("sha256:abc"));
assert_eq!(state.nonce.as_deref(), Some("nonce-001"));

Fields

domain: String

Lower-cased host the state was bound to.

signature: Option<String>

Fingerprint signature captured at session start.

nonce: Option<String>

Session nonce issued at session start (when applicable).

captured_at_epoch_ms: u64

Unix epoch milliseconds when the state was captured.

Implementations

impl ReplayDefenseState

pub fn new( domain: &str, signature: Option<&str>, nonce: Option<&str>, captured_at_epoch_ms: u64, ) -> Self

Build a state record.

pub fn with_fingerprint( domain: &str, signature: &str, nonce: Option<&str>, captured_at_epoch_ms: u64, ) -> Self

Build a state record that captures a fingerprint + nonce for domain at the current wall-clock.

pub fn capture_now( domain: &str, signature: Option<&str>, nonce: Option<&str>, ) -> Self

Build a state record at the current wall-clock.

Trait Implementations

impl Clone for ReplayDefenseState

fn clone(&self) -> ReplayDefenseState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplayDefenseState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReplayDefenseState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReplayDefenseState

fn eq(&self, other: &ReplayDefenseState) -> 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 Serialize for ReplayDefenseState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
