Enum Error 

pub enum Error {
    PlatformInit(String),
    NoDevicesFound,
    DeviceAccess(String),
    PermissionDenied(String),
    NotSupported(String),
    Io(Error),
}

The main error type for all-smi library operations.

This enum covers all possible error conditions that can occur when using the all-smi library, from initialization failures to device access issues.

Variants

PlatformInit(String)

Platform initialization failed.

This error occurs when the underlying platform-specific libraries or APIs cannot be initialized (e.g., NVML, IOReport, hl-smi).

NoDevicesFound

No supported devices were found on the system.

This is not necessarily an error condition - it simply indicates that no GPUs, NPUs, or other accelerators were detected.

DeviceAccess(String)

Device access error occurred.

This error occurs when a device was detected but could not be accessed or queried for metrics.

PermissionDenied(String)

Permission denied when accessing device resources.

Some platforms require elevated privileges to access certain metrics (e.g., AMD GPUs on Linux require sudo access).

NotSupported(String)

Feature not supported on this platform.

This error is returned when attempting to use functionality that is not available on the current platform or hardware.

Io(Error)

An I/O error occurred.

This wraps standard I/O errors that may occur during file system operations or process execution.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
