Device information.

Device context describes the device that caused the event. This is most appropriate for mobile applications.

Fields

name: Annotated<String>

Name of the device.

family: Annotated<String>

Family of the device model.

This is usually the common part of model names across generations. For instance, iPhone would be a reasonable family, so would be Samsung Galaxy.

model: Annotated<String>

Device model.

This, for example, can be Samsung Galaxy S3.

model_id: Annotated<String>

Device model (internal identifier).

An internal hardware revision to identify the device exactly.

arch: Annotated<String>

Native cpu architecture of the device.

battery_level: Annotated<f64>

Current battery level in %.

If the device has a battery, this can be a floating point value defining the battery level (in the range 0-100).

orientation: Annotated<String>

Current screen orientation.

This can be a string portrait or landscape to define the orientation of a device.

manufacturer: Annotated<String>

Manufacturer of the device.

brand: Annotated<String>

Brand of the device.

(e.g.: 800x600, 3040x1444)

screen_width_pixels: Annotated<u64>

Width of the screen in pixels.

screen_height_pixels: Annotated<u64>

Height of the screen in pixels.

screen_dpi: Annotated<u64>

Screen density as dots-per-inch.

online: Annotated<bool>

Whether the device was online or not.

charging: Annotated<bool>

Whether the device was charging or not.

low_memory: Annotated<bool>

Whether the device was low on memory.

simulator: Annotated<bool>

Simulator/prod indicator.

memory_size: Annotated<u64>

Total memory available in bytes.

free_memory: Annotated<u64>

How much memory is still available in bytes.

usable_memory: Annotated<u64>

How much memory is usable for the app in bytes.

storage_size: Annotated<u64>

Total storage size of the device in bytes.

free_storage: Annotated<u64>

How much storage is free in bytes.

external_storage_size: Annotated<u64>

Total size of the attached external storage in bytes (eg: android SDK card).

external_free_storage: Annotated<u64>

Free size of the attached external storage in bytes (eg: android SDK card).

boot_time: Annotated<String>

Indicator when the device was booted.

timezone: Annotated<String>

Timezone of the device.

locale: Annotated<String>

ISO 639-1 code of the locale the device is set to.

processor_count: Annotated<u64>

Number of “logical processors”.

For example, 8.

cpu_description: Annotated<String>

CPU description.

For example, Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz.

processor_frequency: Annotated<u64>

Processor frequency in MHz.

Note that the actual CPU frequency might vary depending on current load and power conditions, especially on low-powered devices like phones and laptops.

device_type: Annotated<String>

Kind of device the application is running on.

For example, Unknown, Handheld, Console, Desktop.

battery_status: Annotated<String>

Status of the device’s battery.

For example, Unknown, Charging, Discharging, NotCharging, Full.

device_unique_identifier: Annotated<String>

Unique device identifier.

supports_vibration: Annotated<bool>

Whether vibration is available on the device.

supports_accelerometer: Annotated<bool>

Whether the accelerometer is available on the device.

supports_gyroscope: Annotated<bool>

Whether the gyroscope is available on the device.

supports_audio: Annotated<bool>

Whether audio is available on the device.

supports_location_service: Annotated<bool>

Whether location support is available on the device.

uuid: Annotated<Uuid>

UUID of the device.

other: Object<Value>

Additional arbitrary fields for forwards compatibility

Trait Implementations

impl Clone for DeviceContext

fn clone(&self) -> DeviceContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceContext

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

Formats the value using the given formatter.

impl Default for DeviceContext

fn default() -> DeviceContext

Returns the “default value” for a type.

impl DefaultContext for DeviceContext

fn default_key() -> &'static str

The default key at which this context resides in Contexts.

fn from_context(context: Context) -> Option<Self>

Converts this context type from a generic context type.

fn cast(context: &Context) -> Option<&Self>

Casts a reference to this context type from a generic context type.

fn cast_mut(context: &mut Context) -> Option<&mut Self>

Casts a mutable reference to this context type from a generic context type.

fn into_context(self) -> Context

Boxes this context type in the generic context wrapper.

impl Empty for DeviceContext

fn is_empty(&self) -> bool

Returns whether this value is empty.

fn is_deep_empty(&self) -> bool

Returns whether this value is empty or all of its descendants are empty.

impl FromValue for DeviceContext

fn from_value(__value: Annotated<Value>) -> Annotated<Self>

Creates a meta structure from an annotated boxed value.

impl IntoValue for DeviceContext

fn into_value(self) -> Value

Boxes the meta structure back into a value.

fn serialize_payload<S>( &self, __serializer: S, __behavior: SkipSerialization, ) -> Result<S::Ok, S::Error>
