--- title: Device summary: The device data associated with a particular User-Agent string. url: https://www.fastly.com/documentation/reference/compute/sdks/rust/fastly/device_detection/struct.Device/ --- **Kind:** Struct **Module:** [device_detection](https://www.fastly.com/documentation/reference/compute/sdks/rust/fastly/device_detection/) **Package:** fastly 0.13.1 **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#64 ```rust pub struct Device { /* private fields */ } ``` The device data associated with a particular User-Agent string. ## Methods ### brand **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#83 ```rust fn brand(&self) -> Option<&str> ``` The brand of the client device, possibly different from the manufacturer of that device. **Parameters** - `self`: `&Self` **Returns** `Option<&str>` ### device_name **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#74 ```rust fn device_name(&self) -> Option<&str> ``` The name of the client device. **Parameters** - `self`: `&Self` **Returns** `Option<&str>` ### hwtype **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#104 ```rust fn hwtype(&self) -> Option<&str> ``` A string representation of the primary client platform hardware. The most commonly used device types are also identified via boolean variables. Because a device may have multiple device types and this variable only has the primary type, we recommend using the boolean variables for logic and using this string representation for logging. **Parameters** - `self`: `&Self` **Returns** `Option<&str>` ### is_bot **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#218 ```rust fn is_bot(&self) -> Option ``` The client's `User-Agent` was recognized as belonging to a bot. **Parameters** - `self`: `&Self` **Returns** `Option` ### is_desktop **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#169 ```rust fn is_desktop(&self) -> Option ``` The client is a desktop web browser. **Parameters** - `self`: `&Self` **Returns** `Option` ### is_downloader **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#223 ```rust fn is_downloader(&self) -> Option ``` The client's `User-Agent` was recognized as belonging to a downloader. **Parameters** - `self`: `&Self` **Returns** `Option` ### is_ereader **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#112 ```rust fn is_ereader(&self) -> Option ``` The client device is a reading device (like a Kindle). **Parameters** - `self`: `&Self` **Returns** `Option` ### is_feedreader **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#228 ```rust fn is_feedreader(&self) -> Option ``` The client's `User-Agent` was recognized as belonging to a feedreader. **Parameters** - `self`: `&Self` **Returns** `Option` ### is_gameconsole **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#120 ```rust fn is_gameconsole(&self) -> Option ``` The client device is a video game console (like a PlayStation or Xbox). **Parameters** - `self`: `&Self` **Returns** `Option` ### is_identified **Source:** https://docs.rs/crate/fastly/0.13.1/source/src/device_detection.rs#237 ```rust fn is_identified(&self) -> Option ``` The client's `User-Agent` was identified.
