Struct IotData 

pub struct IotData {
    pub resources: BTreeMap<String, BTreeMap<String, Value>>,
    pub tags: BTreeMap<String, BTreeMap<String, String>>,
    pub singletons: BTreeMap<String, Value>,
    pub relations: BTreeMap<String, Vec<String>>,
    pub seq: u64,
}

Per-account IoT Core control-plane state.

Fields

resources: BTreeMap<String, BTreeMap<String, Value>>

resource_type -> id -> record. The record is the resource’s persisted JSON attributes plus any minted ARN / id / timestamps.

tags: BTreeMap<String, BTreeMap<String, String>>

Resource tags keyed by ARN.

singletons: BTreeMap<String, Value>

Account-scoped singleton configurations keyed by a stable string.

relations: BTreeMap<String, Vec<String>>

Many-to-many relationship sets keyed by a stable string.

seq: u64

Monotonic counter used to mint unique ids within an account.

Implementations

impl IotData

pub fn get_resource(&self, rtype: &str, id: &str) -> Option<&Value>

Fetch a resource record by type + id.

pub fn put_resource(&mut self, rtype: &str, id: &str, record: Value)

Insert / replace a resource record.

pub fn remove_resource(&mut self, rtype: &str, id: &str) -> Option<Value>

Remove a resource record, returning it if present.

pub fn list_resources(&self, rtype: &str) -> Vec<Value>

All records of a type, ordered by id.

pub fn list_resource_entries(&self, rtype: &str) -> Vec<(String, Value)>

All records of a type as (id, record) pairs, ordered by id. Used by list operations whose output element is a plain identifier string (the stored key) rather than a projected object.

pub fn next_seq(&mut self) -> u64

Next unique sequence value for id minting.

Trait Implementations

impl AccountState for IotData

fn new_for_account(_account_id: &str, _region: &str, _endpoint: &str) -> Self

Create a fresh, empty state for the given account.

fn inherit_from(&mut self, _sibling: &Self)

Called after a new account state is created via MultiAccountState::get_or_create, with a reference to an existing sibling state. Services can override this to propagate shared resources (e.g. body caches) to the new state.

impl Clone for IotData

fn clone(&self) -> IotData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IotData

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

Formats the value using the given formatter.

impl Default for IotData

fn default() -> IotData

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IotData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for IotData

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
