User-provided input files with the Rust SDK

//! User-provided input files with the Rust SDK.

//! The request attaches a CSV as an input file. Text-like files are previewed in
//! the prompt and can be paginated with the built-in file tools when the agentic
//! runtime is active.

//! Run with: `cargo run --release --features code-execution --example file_inputs -p mistralrs`
