Struct ConfigService 

pub struct ConfigService { /* private fields */ }

Configuration and secrets service.

Stores configuration values at /kernel/config/{namespace}/{key} and secrets at /kernel/secrets/{namespace}/{key} (encrypted at rest). Supports change notification via subscriptions.

Implementations

impl ConfigService

pub fn new(encryption_key: [u8; 32]) -> Self

Create a new config service with a given encryption key.

pub fn new_default() -> Self

Create a config service with a default (zero) encryption key (testing).

pub fn set( &self, namespace: &str, key: &str, value: Value, changed_by: Pid, ) -> Result<(), KernelError>

Set a configuration value.

pub fn get(&self, namespace: &str, key: &str) -> Option<Value>

Get a configuration value.

pub fn delete( &self, namespace: &str, key: &str, changed_by: Pid, ) -> Result<(), KernelError>

Delete a configuration value.

pub fn list_keys(&self, namespace: &str) -> Vec<String>

List all config keys in a namespace.

pub fn set_typed( &self, namespace: &str, key: &str, value: ConfigValue, changed_by: Pid, ) -> Result<(), KernelError>

Store a typed configuration value.

pub fn get_typed(&self, namespace: &str, key: &str) -> Option<ConfigEntry>

Retrieve a typed configuration entry.

pub fn list(&self, namespace: &str) -> Vec<ConfigEntry>

List all typed entries in a namespace.

pub fn delete_typed(&self, namespace: &str, key: &str, changed_by: Pid) -> bool

Delete a typed configuration entry. Returns true if it existed.

pub fn subscribe(&self, namespace: &str) -> Arc<RwLock<Vec<ConfigChange>>>

Subscribe to changes in a namespace.

Returns a shared reference to the change queue. Callers can read accumulated changes from the returned Arc<RwLock<Vec<ConfigChange>>>.

pub fn set_secret( &self, namespace: &str, key: &str, value: &[u8], scoped_to: Vec<Pid>, ) -> Result<(), KernelError>

Store an encrypted secret.

pub fn get_secret( &self, namespace: &str, key: &str, requester_pid: Pid, ) -> Result<Vec<u8>, KernelError>

Retrieve a secret (decrypted). Checks PID authorization and expiry.

pub fn change_log(&self) -> Vec<ConfigChange>

Get the change log (for auditing).

pub fn set_count(&self) -> u64

Total number of config sets performed.
