Trait ImageReader 

pub trait ImageReader {
    type Error;

    // Required method
    fn apply<P: AsRef<Path> + Send + Sync>(
        &self,
        imgs: impl IntoIterator<Item = P>,
    ) -> Result<Vec<RgbImage>, Self::Error>;

    // Provided method
    fn read_single<P: AsRef<Path> + Send + Sync>(
        &self,
        img_path: P,
    ) -> Result<RgbImage, Self::Error>
       where Self::Error: From<OCRError> { ... }
}

Trait for reading images.

This trait defines the interface for reading images from paths.

Required Associated Types

type Error

The error type of this image reader.

Required Methods

fn apply<P: AsRef<Path> + Send + Sync>( &self, imgs: impl IntoIterator<Item = P>, ) -> Result<Vec<RgbImage>, Self::Error>

Applies the image reader to the given paths.

Arguments

• imgs - An iterator of paths to the images to read.

Returns

A Result containing a vector of RGB images or an error.

Constraints

• P must implement AsRef<Path> + Send + Sync.

Provided Methods

fn read_single<P: AsRef<Path> + Send + Sync>( &self, img_path: P, ) -> Result<RgbImage, Self::Error>

where Self::Error: From<OCRError>,

Reads a single image from the given path.

Arguments

• img_path - The path to the image to read.

Returns

A Result containing the RGB image or an error.

Constraints

• P must implement AsRef<Path> + Send + Sync.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
