Struct Attr 

pub struct Attr<M: Model> { /* private fields */ }

An attribute of a single device, together with the last value written to it, which Tango keeps aside from the model, and its configuration on that device. Its definition is shared the way that of a [Command] is.

Implementations

impl<M: Model> Attr<M>

pub fn name(&self) -> &str

The name of that attribute, as its definition gave it.

pub fn config(&self) -> AttrConfig

The configuration of that attribute on its device.

pub fn is_memorized(&self) -> bool

Whether that attribute is memorized, see AttrMemorized.

pub fn info(&self) -> Result<AttrInfo>

What a client is told of that attribute: what it may read and change of its configuration, and what its definition advertises of its data.

A definition advertising neither a kind nor a format, which only one built out of a raw handler and given neither can be, has nothing to tell a client of its data and is answered with an error rather than with a guess.

An attribute whose configuration could not be applied is described all the same, with what could be, so that a client can still see what it is configured with.

TODO: AttrMode::ReadWithWrite cannot be derived from the handlers, the write attribute it is paired with having to be named; it needs its own definition.
