cargo install fails — whisper-rs 0.13 incompatible with current whisper.cpp

[Ayyankhan101]

Problem

cargo install opencode-voice fails with 71 compilation errors in whisper-rs. All errors are:

error[E0609]: no field `greedy` on type `whisper_full_params`
error[E0609]: no field `beam_search` on type `whisper_full_params`
error[E0609]: no field `n_threads` on type `whisper_full_params`
... (71 total)

The whisper_full_params struct in whisper-rs-sys only exposes _address (opaque), meaning the Rust FFI bindings no longer match the whisper.cpp struct layout.

Environment

• Rust: 1.97.1 (stable)
• OS: macOS (darwin)
• whisper-rs: 0.13.2 (pinned in Cargo.toml)
• whisper-rs 0.16.0 is available on crates.io

Suggested fix

Bump whisper-rs dependency from "0.13" to "0.16" in Cargo.toml. The high-level API (FullParams, WhisperContext, WhisperState) used in src/transcribe/engine.rs appears stable between versions.
