Struct Context

pub struct Context { /* private fields */ }

Context implementation

• selfId The ID of the device that this context is for.

• local_sensor The values perceived by the local sensors of the device.

• nbr_sensor The values perceived by the sensors for each neighbor of the device.

• exports All the export that are available to the device.

Implementations

impl Context

pub fn new( self_id: i32, local_sensor: LocalSensors, nbr_sensor: NbrSensors, exports: Exports, ) -> Self

Create new Context of a device from the given parameters.

Arguments

• self_id - the ID of the device

• local_sensor - The values perceived by the local sensors of the device.

• nbr_sensor - The values perceived by the sensors for each neighbor of the device.

• exports - All the export that are available to the device.

Returns

The new Context.

pub fn self_id(&self) -> &i32

pub fn exports(&self) -> &Exports

pub fn put_export(&mut self, id: i32, data: Export)

Add an export of a device to the context.

Arguments

• id the ID of the device
• data the export of the device

pub fn read_export_value<A: 'static + FromStr + Clone>( &self, id: &i32, path: &Path, ) -> Result<A>

Read the value corresponding to the given path from the export of a device.

Arguments

• id the ID of the device
• path the path to the value

Generic Parameters

• A the type of the value to return. It must have a 'static lifetime.

Returns

An Option of the value if it exists

pub fn local_sensors(&self) -> &LocalSensors

pub fn local_sense<A: 'static>(&self, local_sensor_id: &SensorId) -> Option<&A>

Get the value of the given sensor.

Arguments

• name the name of the sensor

Generic Parameters

• A the type of the value to return. It must have a 'static lifetime.

Returns

An Option of the value if it exists

pub fn nbr_sensors(&self) -> &NbrSensors

pub fn nbr_sense<A: 'static>( &self, sensor_id: &SensorId, nbr_id: &i32, ) -> Option<&A>

Get the value of the given sensor for the given neighbor.

Arguments

• sensor_id the neighbor sensor id
• nbr_id the neighbor id

Generic Parameters

• A the type of the value to return. It must have a 'static lifetime.

Returns

An Option of the value if it exists

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.
