Struct CoapResource

pub struct CoapResource<D: Any + ?Sized + Debug> { /* private fields */ }

Representation of a CoapResource that can be requested from a server.

Implementations

impl<D: Any + ?Sized + Debug> CoapResource<D>

pub fn new<C: Into<Box<D>>>( uri_path: &str, user_data: C, notify_con: bool, ) -> CoapResource<D>

Creates a new CoapResource for the given uri_path.

Handlers that are associated with this resource have to be able to take a reference to the provided user_data value as their first value.

The notify_con parameter specifies whether observe notifications originating from this resource are sent as confirmable or non-confirmable.

pub fn notify_observers(&self) -> bool

Notify any observers about changes to this resource.

pub fn set_get_observable(&self, observable: bool)

Sets whether this resource can be observed by clients according to RFC 7641.

pub fn set_observe_notify_confirmable(&self, confirmable: bool)

Sets whether observe notifications for this resource should be sent as confirmable or non-confirmable CoAP messages.

pub fn user_data(&self) -> Ref<'_, D>

Returns the user data associated with this resource.

pub fn user_data_mut(&self) -> RefMut<'_, D>

Mutably returns the user data associated with this resource.

pub unsafe fn restore_from_raw( raw_resource: *mut coap_resource_t, ) -> CoapResource<D>

Restores a resource from its raw coap_resource_t.

Safety

The supplied pointer must point to a valid coap_resource_t instance that has a Rc<RefCell<CoapResourceInner<D>>> as its user data.

pub fn set_method_handler<H: Into<CoapRequestHandler<D>>>( &self, code: CoapRequestCode, handler: Option<H>, )

Sets the handler function for a given method code.

pub fn add_attr(&self, name: &str, val: Option<&str>)

Adds an attribute with a name and an optional value to a CoAP resource object.

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

Formats the value using the given formatter.
