Struct hidapi::HidApi [−][src]
pub struct HidApi { /* fields omitted */ }
Expand description
Object for handling hidapi context and implementing RAII for it. Only one instance can exist at a time.
Implementations
Initializes the hidapi.
Will also initialize the currently available device list.
Refresh devices list and information about them (to access them use
device_list()
method)
👎 Deprecated
Returns vec of objects containing information about connected devices
Deprecated. Use HidApi::device_list()
instead.
Returns iterator containing information about attached HID devices.
Open a HID device using a Vendor ID (VID) and Product ID (PID).
When multiple devices with the same vid and pid are available, then the first one found in the internal device list will be used. There are however no guarantees, which device this will be.
Open a HID device using a Vendor ID (VID), Product ID (PID) and a serial number.
The path name be determined by inspecting the device list available with HidApi::devices()
Alternatively a platform-specific path name can be used (eg: /dev/hidraw0 on Linux).
Get the last non-device specific error, which happened in the underlying hidapi C library.
To get the last device specific error, use HidDevice::check_error
.
The Ok()
variant of the result will contain a HidError::HidApiError.
When Err()
is returned, then acquiring the error string from the hidapi C
library failed. The contained HidError is the cause, why no error could
be fetched.
