Xargo is a CLI tool that builds and manages Rust sysroots, letting you cross-compile the standard library (core/std) for targets without prebuilt binaries, such as bare-metal ARM targets. It also supports building customized std crates with specific compiler flags and features.

Use cases

  • cross compile rust for thumbv6m-none-eabi bare metal target
  • build rust core crate for a target without binary releases
  • customize std with panic=abort for embedded rust
  • build rust no_std project for microcontroller
  • manage rust sysroots for cross compilation

When to choose

  • cross-compiling Rust to bare-metal or no_std targets lacking prebuilt std
  • needing a customized std built with specific flags or features

When to avoid

  • modern Rust with build-std nightly feature, which replaces xargo
  • ordinary hosted-target Rust development that never needs custom sysroots
