Struct TextLineClasPredictorBuilder 

pub struct TextLineClasPredictorBuilder { /* private fields */ }

Builder for text line classifier

This struct provides a builder pattern for creating a text line classifier with custom configuration options.

Implementations

impl TextLineClasPredictorBuilder

pub fn new() -> Self

Creates a new text line classifier builder

Initializes a new instance of the text line classifier builder with default configuration options.

Returns

A new instance of TextLineClasPredictorBuilder

pub fn model_path(self, model_path: impl Into<PathBuf>) -> Self

Sets the model path

pub fn model_name(self, model_name: impl Into<String>) -> Self

Sets the model name

pub fn batch_size(self, batch_size: usize) -> Self

Sets the batch size

pub fn enable_logging(self, enable: bool) -> Self

Enables or disables logging

pub fn ort_session(self, config: OrtSessionConfig) -> Self

Sets the ONNX Runtime session configuration

pub fn session_pool_size(self, size: usize) -> Self

Sets the session pool size for concurrent predictions (>=1)

pub fn topk(self, topk: usize) -> Self

Sets the number of top predictions to return

Specifies how many of the top predictions to return for each image.

Arguments

• topk - Number of top predictions to return

Returns

The updated builder instance

pub fn input_shape(self, input_shape: (u32, u32)) -> Self

Sets the input shape for the model

Specifies the input shape (width, height) that the model expects.

Arguments

• input_shape - Input shape as (width, height)

Returns

The updated builder instance

pub fn build(self, model_path: &Path) -> OcrResult<TextLineClasPredictor>

Builds the text line classifier

Creates a new instance of the text line classifier with the configured options.

Arguments

• model_path - Path to the ONNX model file

Returns

A new instance of TextLineClasPredictor or an error if building fails

Trait Implementations

impl Default for TextLineClasPredictorBuilder

fn default() -> Self

Creates a new text line classifier builder with default settings

This is equivalent to calling TextLineClasPredictorBuilder::new().
