Trait OcrBackend 

pub trait OcrBackend: Send + Sync {
    // Required methods
    fn recognize(
        &self,
        image_data: &[u8],
        width: u32,
        height: u32,
    ) -> Result<OcrResult, OcrError>;
    fn name(&self) -> &str;
}

Pluggable OCR backend.

Implementations receive raw RGB pixel data and return recognized text. Implementations must be Send + Sync so they can be held in a static or shared across threads.

Required Methods

fn recognize( &self, image_data: &[u8], width: u32, height: u32, ) -> Result<OcrResult, OcrError>

Recognize text in a rasterized page image.

Arguments

• image_data — raw RGB pixels, row-major, 3 bytes per pixel.
• width — image width in pixels.
• height — image height in pixels.

fn name(&self) -> &str

Short identifier shown in test metadata (e.g. "ocrs", "mistral").
