Embedded Rust

Embedded Rust is the domain of writing Rust for firmware and hardware-facing systems, especially no_std and bare-metal targets where ownership, volatile access, and interrupt-safe sharing must model the machine directly.

Concepts

• Embedded Rust Basics
• no_std
• Bare-Metal Programming
• O
• Peripheral Access Crates
• Interrupts and Concurrency (Embedded)

Patterns

• Critical Sections in Embedded Rust
• Heapless Collections in Embedded Rust

Antipatterns

• Unsynchronized static mut in Interrupts

Source Trail

Start with embedded-book, then read the notes in this order: Embedded Rust Basics, no_std, Bare-Metal Programming, O, Peripheral Access Crates, and Interrupts and Concurrency (Embedded). The patterns and antipattern explain the main design pressure: hardware is mutable global state, but Rust code should expose it through narrow, synchronized ownership.
