Struct DeviceConfig 

pub struct DeviceConfig {
    pub cuda_device: usize,
    pub force_cpu: bool,
    pub crate_name: Option<String>,
}

Configuration for device selection.

Fields

• cuda_device: Preferred CUDA device ordinal (default: 0)
• force_cpu: Force CPU execution regardless of GPU availability
• crate_name: Name of the crate for logging (used in warnings)

Fields

cuda_device: usize

Preferred CUDA device ordinal.

force_cpu: bool

Force CPU execution (disables GPU).

crate_name: Option<String>

Crate name for logging (appears in warnings).

Implementations

impl DeviceConfig

pub fn new() -> Self

Create a new device configuration with defaults.

pub fn with_cuda_device(self, ordinal: usize) -> Self

Set the preferred CUDA device ordinal.

pub fn with_force_cpu(self, force: bool) -> Self

Force CPU execution.

pub fn with_crate_name(self, name: impl Into<String>) -> Self

Set crate name for logging.

pub fn from_env() -> Self

Build configuration from environment variables.

Checks these environment variables (in order):

1. RUST_AI_FORCE_CPU / RUST_AI_CUDA_DEVICE
2. AXOLOTL_FORCE_CPU / AXOLOTL_CUDA_DEVICE (legacy)
3. VSA_OPTIM_FORCE_CPU / VSA_OPTIM_CUDA_DEVICE (legacy)

Trait Implementations

impl Clone for DeviceConfig

fn clone(&self) -> DeviceConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DeviceConfig

fn default() -> DeviceConfig

Returns the “default value” for a type.
