Installation and Features

Rust Requirement

The source currently uses:

#![feature(generic_const_exprs)]
#![allow(incomplete_features)]

Nightly Rust is therefore required. The main use case is fixed-size caches such as ArmKineCache<N>, which stores N + 1 link frames.

Cargo Dependency

[dependencies]
robot_behavior = { version = "0.6.0", git = "ssh://git@github.com/Robot-Exp-Platform/robot_behavior.git", rev = "781245ca4d662a693cfb24955328a5a610859591" }

These pages describe the current development source; the version string alone does not prove that a crates.io release contains the same API. For source-aligned graph development, use the matching local/git revision and enable features = ["roplat"]. See Roplat integration.

The prepared versions are robot_behavior 0.6.0 and roplat 0.3.0; neither has been uploaded to crates.io. The published roplat 0.2.2 predates the current execution API and cannot replace the pinned core source. Independent drivers retain complete pinned Git dependency declarations. The integration workspace applies path patches for those exact Git sources at its root. SSH uses the caller's existing GitHub access; set CARGO_NET_GIT_FETCH_WITH_CLI=true to use local Git/SSH credentials without putting them in manifests. Cargo may fetch optional dependency metadata even when the feature is off.

Features

Feature	Purpose	Notes
`default`	empty	the core Rust traits need no extra feature
`roplat`	enables `robot_behavior::roplat` and the roplat dependency	off by default
`ffi`	enables the FFI module gate	base gate
`to_py`	`ffi` + `pyo3`	Python binding support
`to_cxx`	`ffi` + `cxx`	C++ binding support
`to_c`	`ffi`	C-facing gate

!!! warning FFI macros and examples are still migrating. The main documentation follows the current Rust trait API. Before relying on FFI, run cargo check --features to_py or the corresponding target feature for your driver.

Verification Commands

From the drives workspace:

cargo check -p robot_behavior --no-default-features
cargo check -p robot_behavior --features roplat
cargo test -p robot_behavior --lib

From a standalone robot_behavior checkout:

cargo check --no-default-features
cargo check --features roplat
cargo test --lib
