Struct ObjectDatabase 

pub struct ObjectDatabase { /* private fields */ }

A collection of BACnet objects, keyed by ObjectIdentifier.

Enforces BACnet Clause 12.11.12: Object_Name must be unique within a device. Maintains secondary indexes for O(1) name lookup and O(1) type lookup.

Implementations

impl ObjectDatabase

pub fn new() -> Self

Create an empty database.

pub fn add(&mut self, object: Box<dyn BACnetObject>) -> Result<(), Error>

Add an object to the database.

Returns Err if another object already has the same object_name() (BACnet Clause 12.11.12 requires unique names within a device). Replacing an object with the same OID is allowed (the old object is removed).

pub fn find_by_name(&self, name: &str) -> Option<&dyn BACnetObject>

Look up an object by its name. O(1) via the name index.

pub fn check_name_available( &self, oid: &ObjectIdentifier, new_name: &str, ) -> Result<(), Error>

Check whether new_name is available for object oid.

Returns Ok(()) if the name is unused or already belongs to oid. Returns Err(DUPLICATE_NAME) if another object owns the name.

pub fn update_name_index(&mut self, oid: &ObjectIdentifier)

Update the name index after a successful Object_Name write.

Call this after write_property(OBJECT_NAME, …) succeeds.

pub fn get(&self, oid: &ObjectIdentifier) -> Option<&dyn BACnetObject>

Get a shared reference to an object by identifier.

pub fn get_mut( &mut self, oid: &ObjectIdentifier, ) -> Option<&mut Box<dyn BACnetObject>>

Get a mutable reference to an object by identifier.

pub fn remove( &mut self, oid: &ObjectIdentifier, ) -> Option<Box<dyn BACnetObject>>

Remove an object by identifier.

pub fn list_objects(&self) -> Vec<ObjectIdentifier>

List all object identifiers in the database.

pub fn find_by_type(&self, object_type: ObjectType) -> Vec<ObjectIdentifier>

Find all objects of a given type.

Returns a Vec of ObjectIdentifiers whose object type matches object_type. Useful for WhoHas, object enumeration, and similar queries.

pub fn iter_objects( &self, ) -> impl Iterator<Item = (ObjectIdentifier, &dyn BACnetObject)>

Iterate over all (ObjectIdentifier, &dyn BACnetObject) pairs.

Avoids the double-lookup pattern of list_objects() followed by get().

pub fn len(&self) -> usize

Number of objects in the database.

pub fn is_empty(&self) -> bool

Whether the database is empty.

Trait Implementations

impl Default for ObjectDatabase

fn default() -> Self

Returns the “default value” for a type.
