Struct DeviceIndex

Source 
#[repr(transparent)]
pub struct DeviceIndex(pub i8);
Expand description

Binding for c10::DeviceIndex.

An index representing a specific device; e.g., the 1 in GPU 1. A DeviceIndex is not independently meaningful without knowing the DeviceType it is associated; try to use Device rather than DeviceIndex directly.

Marked repr(transparent) because c10::DeviceType is really just a type alias for int8_t, so we want to guarantee that the representation is identical to that.
