Struct ObjectDictionary 

pub struct ObjectDictionary<const N: usize> { /* private fields */ }

An object dictionary holding up to N entries, addressed by (index, subindex).

Implementations

impl<const N: usize> ObjectDictionary<N>

pub const fn new() -> Self

Create an empty object dictionary.

pub fn insert(&mut self, addr: Address, entry: Entry) -> Result<()>

Insert or replace the entry at addr.

Returns Error::DictionaryFull when capacity N is exhausted.

pub fn entry(&self, addr: Address) -> Option<&Entry>

Borrow the raw entry at addr, ignoring access rights.

pub fn read(&self, addr: Address) -> Result<Value>

Read the value at addr, honouring access rights.

Returns Error::ObjectNotFound if absent, or Error::WriteOnly if the object is not readable.

pub fn write(&mut self, addr: Address, value: Value) -> Result<()>

Write value at addr, honouring access rights and the object’s data type.

Returns Error::ObjectNotFound if absent, Error::ReadOnly if not writable, or Error::TypeMismatch if value’s type differs from the stored object’s type.
