Struct ReadReq 

pub struct ReadReq<'a>(/* private fields */);

A request to read attributes and events from a Matter device.

Corresponds to the ReadRequestMessage TLV structure in the Interaction Model.

Implementations

impl<'a> ReadReq<'a>

pub const fn new(element: TLVElement<'a>) -> ReadReq<'a>

Create a new ReadReq from a TLVElement.

pub fn attr_requests( &self, ) -> Result<Option<TLVContainer<'a, AttrPath, ArrayContainer>>, Error>

Return the attribute requests in this read request, if any.

pub fn event_requests( &self, ) -> Result<Option<TLVContainer<'a, EventPath, ArrayContainer>>, Error>

Return the event requests in this read request, if any.

pub fn event_filters( &self, ) -> Result<Option<TLVContainer<'a, EventFilter, ArrayContainer>>, Error>

Return the event filters in this read request, if any.

pub fn fabric_filtered(&self) -> Result<bool, Error>

Return Ok(true) if this read request is fabric-filtered.

pub fn dataver_filters( &self, ) -> Result<Option<TLVContainer<'a, DataVersionFilter, ArrayContainer>>, Error>

Return the data version filters in this read request, if any.
