Struct AppContext

    pub app_name: String,
    pub app_id: String,
    pub channel: String,
    pub app_version: Option<String>,
    pub app_build: Option<String>,

}

The AppContext object represents the parameters and characteristics of the consuming application that we are interested in for targeting purposes. The app_name and channel fields are not optional as they are expected to be provided by all consuming applications as they are used in the top-level targeting that help to ensure that an experiment is only processed by the correct application.

Definitions of the fields are as follows:

• app_name: This is the name of the application (e.g. “Fenix” or “Firefox iOS”)
• app_id: This is the application identifier, especially for mobile (e.g. “org.mozilla.fenix”)
• channel: This is the delivery channel of the application (e.g “nightly”)
• app_version: The user visible version string (e.g. “1.0.3”)
• app_build: The build identifier generated by the CI system (e.g. “1234/A”)
• architecture: The architecture of the device, (e.g. “arm”, “x86”)
• device_manufacturer: The manufacturer of the device the application is running on
• device_model: The model of the device the application is running on
• locale: The locale of the application during initialization (e.g. “es-ES”)
• os: The name of the operating system (e.g. “Android”, “iOS”, “Darwin”, “Windows”)
• os_version: The user-visible version of the operating system (e.g. “1.2.3”)
• android_sdk_version: Android specific for targeting specific sdk versions
• debug_tag: Used for debug purposes as a way to match only developer builds, etc.
• installation_date: The date the application installed the app
• home_directory: The application’s home directory
• custom_targeting_attributes: Contains attributes specific to the application, derived by the application
