Struct TextRegion 

pub struct TextRegion {
    pub bounding_box: BoundingBox,
    pub text: Option<Arc<str>>,
    pub confidence: Option<f32>,
    pub orientation_angle: Option<f32>,
}

A text region containing detection and recognition results.

This struct groups together all the information related to a single detected text region, including the bounding box, recognized text, confidence score, and orientation angle. This design eliminates the need for parallel vectors and provides better ergonomics for iterating over text regions.

Fields

bounding_box: BoundingBox

The bounding box of the detected text region.

text: Option<Arc<str>>

The recognized text, if recognition was successful. None indicates that recognition failed or was filtered out due to low confidence.

confidence: Option<f32>

The confidence score for the recognized text. None indicates that recognition failed or was filtered out due to low confidence.

orientation_angle: Option<f32>

The text line orientation angle, if orientation classification was performed. None indicates that orientation classification was not performed or failed.

Implementations

impl TextRegion

pub fn new(bounding_box: BoundingBox) -> Self

Creates a new TextRegion with the given bounding box.

The text, confidence, and orientation_angle are initially set to None.

pub fn with_recognition( bounding_box: BoundingBox, text: Option<Arc<str>>, confidence: Option<f32>, ) -> Self

Creates a new TextRegion with detection and recognition results.

pub fn with_all( bounding_box: BoundingBox, text: Option<Arc<str>>, confidence: Option<f32>, orientation_angle: Option<f32>, ) -> Self

Creates a new TextRegion with all fields specified.

pub fn has_text(&self) -> bool

Returns true if this text region has recognized text.

pub fn has_confidence(&self) -> bool

Returns true if this text region has a confidence score.

pub fn has_orientation(&self) -> bool

Returns true if this text region has an orientation angle.

pub fn text_with_confidence(&self) -> Option<(&str, f32)>

Returns the text and confidence as a tuple if both are available.

Trait Implementations

impl Clone for TextRegion

fn clone(&self) -> TextRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextRegion

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

Formats the value using the given formatter.
