Walkthrough

The changes update the console output formatting and informational print statements across several example Rust files. These modifications include clearer headers, progress messages, and structured result displays for embedding, fill-mask, sentiment analysis, text generation, text generation with tools, and zero-shot classification examples. No core logic or public API changes were made.

Changes

File(s)	Change Summary
examples/embedding.rs	Improved progress and result print statements; simplified main return type via explicit import.
examples/fill_mask.rs	Reformatted output: replaced debug print with structured, labeled prediction list.
examples/sentiment_analysis.rs	Output now uses a formatted summary with headers and confidence score, replacing debug print.
examples/text_generation.rs	Added progress print statements; changed output headers to "===" style for clarity.
examples/text_generation_tools.rs	Updated section headers to clarify which tools are used during text generation.
examples/zero_shot.rs	Adjusted print statements for improved spacing and removed unnecessary trailing newline.

Poem

In the warren of code, new prints now gleam,
With headers and spacing—a formatting dream!
Each example speaks clearer, with structure and cheer,
Console bunnies rejoice, for the output’s sincere.
From embeddings to text, our messages delight—
Hopping through clarity, everything’s right!
🐇✨
