Asynchronous wrapper for TensorRT 8.

async-tensorrt is an async wrapper for TensorRT.

This project is still a work-in-progress, and will contain bugs. Some parts of the API have not been flushed out yet. Use with caution.

Make sure you have the necessary dependencies installed:

• CUDA toolkit 11 or later.
• TensorRT 8 or later.

Then, add the following to your dependencies in Cargo.toml:

async-tensorrt = "0.7"

This crate is intentionally unsafe. Due to the limitations of how async Rust currently works, usage of the async interface of this crate can cause undefined behavior in some rare cases. It is up to the user of this crate to prevent this from happening by following these rules:

• No futures produced by functions in this crate may be leaked (either by std::mem::forget or otherwise).
• Use a well-behaved runtime (one that will not forget your future) like Tokio or async-std.

Internally, the Future type in this crate schedules a CUDA call on a separate runtime thread. To make the API as ergonomic as possible, the lifetime bounds of the closure (that is sent to the runtime) are tied to the future object. To enforce this bound, the future will block and wait if it is dropped. This mechanism relies on the future being driven to completion, and not forgotten. This is not necessarily guaranteed. Unsafety may arise if either the runtime gives up on or forgets the future, or the caller manually polls the future, then forgets it.
