Struct HwDeviceInfo 

pub struct HwDeviceInfo {
    pub name: String,
    pub driver_version: Option<String>,
    pub api_version: Option<String>,
    pub total_memory_bytes: Option<u64>,
    pub extra: Vec<(String, String)>,
    pub codecs: Vec<HwCodecCaps>,
}

A single hardware engine the backend can dispatch to. For NVIDIA / Vulkan / VA-API DRM, this is one entry per physical GPU. For VDPAU on a single-X11-display system, this is one entry per X screen. For VideoToolbox on Apple Silicon, this is one entry per SoC.

Fields

name: String

Human-readable device name. e.g. “NVIDIA GeForce RTX 5080”, “Intel(R) UHD Graphics 770”, “Apple M3 Max Media Engine”.

driver_version: Option<String>

Driver / runtime version, if reportable. e.g. “580.95.05”, “Mesa 24.2”, “VideoToolbox (system)”.

api_version: Option<String>

API version the backend speaks. e.g. “CUDA 12.6”, “VDPAU API 1”, “Vulkan 1.4”, “VA-API 1.22”.

total_memory_bytes: Option<u64>

On-card memory in bytes if known. Discrete GPUs report a real figure; integrated and shared-memory engines usually report None.

extra: Vec<(String, String)>

Backend-specific extras keyed by string. e.g. for NVIDIA: ("compute_capability", "12.0"). CLI prints these as key = value in a sub-block. Order is preserved.

codecs: Vec<HwCodecCaps>

Per-codec capabilities for codecs this engine can decode and/or encode.
