Enum DetectionError 

#[non_exhaustive]
pub enum DetectionError {
    ToolNotFound {
        tool: String,
    },
    ToolFailed {
        tool: String,
        exit_code: Option<i32>,
        stderr: String,
    },
    Timeout {
        tool: String,
        timeout_secs: f64,
    },
    ParseError {
        backend: String,
        message: String,
    },
    SysfsReadError {
        path: String,
        message: String,
    },
}

An error encountered during hardware detection.

These are non-fatal — detection continues even when individual backends fail. The registry collects them as crate::AcceleratorRegistry::warnings.

Examples

use ai_hwaccel::DetectionError;

let err = DetectionError::ToolNotFound { tool: "nvidia-smi".into() };
assert!(err.to_string().contains("nvidia-smi"));

let err = DetectionError::Timeout { tool: "hl-smi".into(), timeout_secs: 5.0 };
assert!(err.to_string().contains("timed out"));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ToolNotFound

A required CLI tool was not found on $PATH.

Fields

tool: String

ToolFailed

A CLI tool was found but exited with a non-zero status.

Fields

tool: String

exit_code: Option<i32>

stderr: String

Timeout

A CLI tool did not exit within the allowed timeout.

The process was killed. This is distinct from ToolFailed to allow callers to implement retry logic for transient slowness.

Fields

tool: String

timeout_secs: f64

ParseError

Output from a CLI tool or sysfs file could not be parsed.

Fields

backend: String

message: String

SysfsReadError

A sysfs or procfs path could not be read.

Fields

path: String

message: String

Trait Implementations

impl Clone for DetectionError

fn clone(&self) -> DetectionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DetectionError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DetectionError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DetectionError

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

Formats the value using the given formatter.

impl Error for DetectionError

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 PartialEq for DetectionError

fn eq(&self, other: &DetectionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DetectionError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
