Struct Baseline 

#[non_exhaustive]
pub struct Baseline {
    pub fingerprint: Fingerprint,
    pub previous_ip_prefix: Option<String>,
    pub ip_changed_at: Option<DateTime<Utc>>,
}

What a session is compared against.

Hard identity (browser family, OS, client hints) is fixed at login or step-up. Soft signals (network, country, ASN, anonymity, languages, TLS fingerprint, browser version) follow the client as trusted requests come in.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fingerprint: Fingerprint

The reference fingerprint.

previous_ip_prefix: Option<String>

The network the client was on before the last move.

ip_changed_at: Option<DateTime<Utc>>

When the client last moved network.

Implementations

impl Baseline

pub fn new(fingerprint: Fingerprint) -> Self

A fresh baseline, as set at login and after a completed step-up.

pub fn absorb( &mut self, current: &Fingerprint, now: DateTime<Utc>, checks: &Checks, ) -> bool

Learns soft signals from a request that was let through. Only signals that checks scored are learned, so a route with looser checks cannot slip a change past stricter ones. Hard identity is never learned and missing values never erase known ones. Returns whether anything changed.

Trait Implementations
