Enum RecPreProcessorError 

pub enum RecPreProcessorError {
    EmptyRegions,
    EmptyImage,
    InvalidConfiguration,
    ZeroArea {
        index: usize,
    },
    RegionOutOfBounds {
        index: usize,
        image_dims: (u32, u32),
        region: RecTextRegion,
    },
}

Errors that can be produced by recognition preprocessing.

Variants

EmptyRegions

The provided batch of regions is empty.

EmptyImage

The input image has zero width or height.

InvalidConfiguration

The configuration contains an invalid parameter (e.g. zero height/width).

ZeroArea

A region had zero width or height.

Fields

index: usize

RegionOutOfBounds

A region extended beyond the bounds of the image.

Fields

index: usize

image_dims: (u32, u32)

region: RecTextRegion

Trait Implementations

impl Debug for RecPreProcessorError

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

Formats the value using the given formatter.

impl Display for RecPreProcessorError

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

Formats the value using the given formatter.

impl Error for RecPreProcessorError

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<RecPreProcessorError> for OcrError

fn from(source: RecPreProcessorError) -> Self

Converts to this type from the input type.
