docling_rs 0.1.2

//! Synchronous local file conversion via multipart upload.
//!
//! Demonstrates converting a local file by uploading it to Docling Serve
//! via multipart/form-data. The call blocks until conversion is complete.
//! Also shows how to configure options and target type for file uploads.
//!
//! # Usage
//! ```sh
//! cargo run --example convert_file
//! ```
