Struct ImageContext 

#[non_exhaustive]
pub struct ImageContext {
    pub lat_long_rect: Option<LatLongRect>,
    pub language_hints: Vec<String>,
    pub crop_hints_params: Option<CropHintsParams>,
    pub product_search_params: Option<ProductSearchParams>,
    pub web_detection_params: Option<WebDetectionParams>,
    pub text_detection_params: Option<TextDetectionParams>,
    /* private fields */
}

Image context and/or feature-specific parameters.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

lat_long_rect: Option<LatLongRect>

Not used.

language_hints: Vec<String>

List of languages to use for TEXT_DETECTION. In most cases, an empty value yields the best results since it enables automatic language detection. For languages based on the Latin alphabet, setting language_hints is not needed. In rare cases, when the language of the text in the image is known, setting a hint will help get better results (although it will be a significant hindrance if the hint is wrong). Text detection returns an error if one or more of the specified languages is not one of the supported languages.

crop_hints_params: Option<CropHintsParams>

Parameters for crop hints annotation request.

product_search_params: Option<ProductSearchParams>

Parameters for product search.

web_detection_params: Option<WebDetectionParams>

Parameters for web detection.

text_detection_params: Option<TextDetectionParams>

Parameters for text detection and document text detection.

Trait Implementations

impl Clone for ImageContext

fn clone(&self) -> ImageContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageContext

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

Formats the value using the given formatter.

impl Default for ImageContext

fn default() -> ImageContext

Returns the “default value” for a type.

impl Message for ImageContext

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ImageContext

fn eq(&self, other: &ImageContext) -> 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.
