Struct TokenPolicy 

pub struct TokenPolicy { /* private fields */ }

Per-vendor defaults for the TokenValidator.

Every field is documented in the module docs. The defaults are the values baked into builtin_token_policies; operators can override per-vendor with TokenPolicyTable::with_policy.

Example

use std::time::Duration;
use stygian_charon::token_lifecycle::TokenPolicy;
use stygian_charon::vendor_classifier::VendorId;

let policy = TokenPolicy::default_for(VendorId::Cloudflare);
assert_eq!(policy.default_ttl(), Duration::from_mins(30));
assert!(policy.single_use());

Implementations

impl TokenPolicy

pub fn new( default_ttl: Duration, max_ttl: Duration, require_nonce: bool, single_use: bool, require_session_binding: bool, ) -> Self

Build a TokenPolicy with explicit values. The constructor clamps default_ttl to max_ttl so a caller cannot accidentally build a policy whose default is longer than its maximum.

pub fn with_default_ttl(self, default_ttl: Duration) -> Self

Replace the default TTL. The new value is clamped to the current max_ttl so the policy invariant (max_ttl >= default_ttl) is preserved.

Example

use std::time::Duration;
use stygian_charon::token_lifecycle::TokenPolicy;

let p = TokenPolicy::default_for(stygian_charon::vendor_classifier::VendorId::Cloudflare);
let tighter = p.with_default_ttl(Duration::from_mins(5));
assert_eq!(tighter.default_ttl(), Duration::from_mins(5));

pub fn with_max_ttl(self, max_ttl: Duration) -> Self

Replace the maximum TTL.

Example

use std::time::Duration;
use stygian_charon::token_lifecycle::TokenPolicy;

let p = TokenPolicy::default_for(stygian_charon::vendor_classifier::VendorId::Cloudflare);
let tighter = p.with_max_ttl(Duration::from_mins(20));
assert_eq!(tighter.max_ttl(), Duration::from_mins(20));

pub const fn default_ttl(&self) -> Duration

Default TTL baked into this policy.

pub const fn max_ttl(&self) -> Duration

Maximum TTL the validator will accept.

pub const fn require_nonce(&self) -> bool

Whether per-issuance nonce binding is required.

pub const fn single_use(&self) -> bool

Per-vendor default for the single-use flag.

pub const fn require_session_binding(&self) -> bool

Whether sticky-session binding is required.

pub fn default_for(vendor: VendorId) -> Self

Per-vendor default policy matching the vendor policy table.

Example

use std::time::Duration;
use stygian_charon::token_lifecycle::TokenPolicy;
use stygian_charon::vendor_classifier::VendorId;

assert_eq!(TokenPolicy::default_for(VendorId::Cloudflare).default_ttl(), Duration::from_mins(30));
assert_eq!(TokenPolicy::default_for(VendorId::DataDome).default_ttl(), Duration::from_mins(10));
assert_eq!(TokenPolicy::default_for(VendorId::Unknown).default_ttl(), Duration::from_mins(5));

Trait Implementations

impl Clone for TokenPolicy

fn clone(&self) -> TokenPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TokenPolicy

impl Debug for TokenPolicy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TokenPolicy

impl PartialEq for TokenPolicy

fn eq(&self, other: &TokenPolicy) -> 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 TokenPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
