Struct CudaDeviceInfo 

pub struct CudaDeviceInfo {
    pub index: u32,
    pub name: String,
    pub total_memory: u64,
}

CUDA device information from native driver API

Provides accurate device information including:

• Device name (e.g., “NVIDIA GeForce RTX 4090”)
• Total VRAM in bytes
• Device ordinal

Fields

index: u32

Device ordinal (0-based index)

name: String

Device name from cuDeviceGetName

total_memory: u64

Total VRAM in bytes from cuDeviceTotalMem
