Struct PolicyRegistry 

pub struct PolicyRegistry { /* private fields */ }

Thread-safe registry of named PolicyConfig instances.

• Reads are lock-free via ArcSwap (the active policy can be read from any thread without contention).
• Writes (register/remove/switch) take a brief RwLock on the policy map. Since policy changes are rare (operator-initiated), this is not a contention concern.

Implementations

impl PolicyRegistry

pub fn new() -> Self

Create a new registry with the "standard" policy active.

pub fn active_config(&self) -> PolicyConfig

Get the currently active policy config (lock-free).

pub fn active_name(&self) -> String

Get the name of the currently active policy (lock-free).

pub fn register( &self, name: &str, config: PolicyConfig, ) -> Result<(), PolicyRegistryError>

Register a named policy. Validates before accepting.

Overwrites any existing policy with the same name (except "standard" which is protected).

pub fn remove(&self, name: &str) -> Result<(), PolicyRegistryError>

Remove a named policy. Cannot remove "standard" or the currently active policy.

pub fn set_active( &self, name: &str, ) -> Result<PolicySwitchEvent, PolicyRegistryError>

Switch the active policy to the named policy.

Returns a PolicySwitchEvent recording the transition. The caller is responsible for emitting it to the evidence ledger and resetting conformal calibration windows as needed.

pub fn list(&self) -> Vec<String>

List all registered policy names.

pub fn get(&self, name: &str) -> Option<PolicyConfig>

Get a specific named policy config, if it exists.

pub fn switch_count(&self) -> u64

Total number of policy switches performed.

Trait Implementations

impl Debug for PolicyRegistry

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

Formats the value using the given formatter.

impl Default for PolicyRegistry

fn default() -> Self

Returns the “default value” for a type.
