Struct gcp_client::google::cloud::vision::v1p2beta1::ImageContext

pub struct ImageContext {
    pub lat_long_rect: Option<LatLongRect>,
    pub language_hints: Vec<String>,
    pub crop_hints_params: Option<CropHintsParams>,
    pub web_detection_params: Option<WebDetectionParams>,
}

Image context and/or feature-specific parameters.

Fields

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.

web_detection_params: Option<WebDetectionParams>

Parameters for web detection.

Trait Implementations

impl Clone for ImageContext

fn clone(&self) -> ImageContext

Returns a copy 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 encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<ImageContext> for ImageContext

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
