Enum MlError 

pub enum MlError {
    DeviceUnavailable(String),
    FeatureDisabled(&'static str),
    ModelLoad {
        path: PathBuf,
        reason: String,
    },
    InvalidInput(String),

}

Errors surfaced by oximedia-ml.

Construct user-facing failures with MlError::invalid_input, MlError::preprocess, MlError::postprocess, or MlError::pipeline; the remaining variants are usually produced by the crate itself and matched on at call sites.

Variants

DeviceUnavailable(String)

The requested device is either unknown, unavailable, or built without its feature flag.

FeatureDisabled(&'static str)

A feature required to perform the operation is disabled.

ModelLoad

The model file could not be loaded from disk.

Fields

path: PathBuf

Model path that failed to load.

reason: String

Human-readable reason provided by the backend.

InvalidInput(String)

Input tensor(s) did not match the model’s contract.

Preprocess(String)

Pre-processing failed (e.g. image dimensions don’t fit).

Postprocess(String)

Post-processing failed (e.g. reading an output tensor).

Pipeline

A pipeline sub-component failed to execute.

Fields

stage: &'static str

Pipeline stage that raised the error.

message: String

Descriptive error message.

CacheCapacityZero

The cache capacity was zero, which is invalid.

OnnxRuntime(String)

Underlying ONNX runtime error (feature-gated).

Implementations

impl MlError

pub fn pipeline(stage: &'static str, message: impl Into<String>) -> Self

Convenience constructor for pipeline errors.

pub fn invalid_input(message: impl Into<String>) -> Self

Convenience constructor for invalid input errors.

pub fn preprocess(message: impl Into<String>) -> Self

Convenience constructor for preprocess errors.

pub fn postprocess(message: impl Into<String>) -> Self

Convenience constructor for postprocess errors.

Trait Implementations

impl Debug for MlError

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

Formats the value using the given formatter.

impl Display for MlError

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

Formats the value using the given formatter.

impl Error for MlError

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.
