Trait Implementations

impl AttributeProvider for NoAttributes

fn for_attrs_in_range(
    &mut self,
    _range: HandleRange,
    _f: impl FnMut(&Self, &Attribute<dyn AsRef<[u8]>>) -> Result<(), Error>
) -> Result<(), Error>

Calls a closure f with every attribute whose handle is inside range, ascending.

fn is_grouping_attr(&self, _uuid: AttUuid) -> bool

Returns whether uuid is a valid grouping attribute type that can be used in Read By Group Type requests.

fn group_end(&self, _handle: Handle) -> Option<&Attribute<dyn AsRef<[u8]>>>

Queries the last attribute that is part of the attribute group denoted by the grouping attribute at handle.

fn attr_access_permissions(&self, _handle: Handle) -> AttributeAccessPermissions

Retrieves the permissions for the given attribute.

fn write_attr(&mut self, _handle: Handle, _data: &[u8]) -> Result<(), Error>

Attempts to write data to the given attribute.

fn read_attr_dynamic(
    &mut self,
    _handle: Handle,
    _buffer: &mut [u8]
) -> Option<usize>

If this read is from dynamic data fill the buffer and return the length of the data. If not return None.

fn prepare_write_attr(
    &mut self,
    _handle: Handle,
    _offset: u16,
    _data: &[u8]
) -> Result<(), Error>

In order to write data longer than what would fit one write request the procedure is explained in BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 3, Part F section 3.4.6.

fn execute_write_attr(&mut self, _flags: u8) -> Result<(), Error>

In order to write data longer than what would fit one write request the procedure is explained in BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 3, Part F section 3.4.6.

fn find_information(
    &mut self,
    _range: HandleRange,
    _responder: &mut Sender<'_>
) -> Result<(), Error>

See BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 3, Part F section 3.4.3.1 on what to implement here.
