Features

Features​

The following features are supported in OpEn:

Memory allocators​

You can use the feature rp to use the memory allocator rpmalloc and jem for jemalloc. Using a different allocator can be useful when your application solves optimization problems repeatedly and allocation overhead starts to matter. In performance-sensitive settings, such as embedded optimization, real-time control, or server workloads with many solver calls, an alternative allocator may reduce latency variation and improve throughput.

For example, you can include OpEn as a dependency in your Rust project by adding one of the following entries to your Cargo.toml file:

[dependencies]
optimization-engine = { version = "0.11", features = ["rp"] }

You cannot use both rp and jem.

WebAssembly Support​

warning

In version 0.12.0 of OpEn, wasm was replaced by web-time, so this feature is not supported any more. OpEn can still be used in WebAssembly without the need to specify any features.

If you intend to use OpEn in WebAssembly you need to use the feature wasm.

[dependencies]
optimization-engine = { version = "0.11", features = ["wasm"] }
