Enum VisionError 

#[non_exhaustive]
pub enum VisionError {
    Render(EngineError),
    Model(String),
    Inference(String),
    Output(String),
    InvalidCrop(String),
}

Errors from the vision layer.

#[non_exhaustive]: new failure modes land in a published crate without breaking callers that match with a fallback arm.

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.

Render(EngineError)

The page could not be rendered.

Model(String)

The ONNX model could not be loaded.

Inference(String)

Inference failed.

Output(String)

The model’s output is missing or not f32.

InvalidCrop(String)

The crop bbox covers no pixels.

Trait Implementations

impl Debug for VisionError

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

Formats the value using the given formatter.

impl Display for VisionError

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

Formats the value using the given formatter.

impl Error for VisionError

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<EngineError> for VisionError

fn from(source: EngineError) -> Self

Converts to this type from the input type.
