Domain Embedded

Auto-injects when you're writing embedded Rust for microcontrollers and bare metal systems. Loads your target configuration from .cargo/config.toml and gives you the constraint map for no_std development: no heap means heapless collections, interrupt safety requires Mutex with critical sections, peripheral access goes through HAL ownership patterns. The trace down logic connects domain rules like "no dynamic allocation" directly to crate choices and design patterns. Covers the full stack from PAC registers up through RTIC and Embassy, with specific attention to the static state patterns you need for ISR-safe code. If you're toggling GPIOs or writing firmware, this keeps the embedded constraints front and center.

Embedded Domain

Layer 3: Domain Constraints

Domain Constraints → Design Implications

Domain Rule	Design Constraint	Rust Implication
No heap	Stack allocation	heapless, no Box/Vec
No std	Core only	#![no_std]
Real-time	Predictable timing	No dynamic alloc
Resource limited	Minimal memory	Static buffers
Hardware safety	Safe peripheral access	HAL + ownership
Interrupt safe	No blocking in ISR	Atomic, critical sections

Critical Constraints

No Dynamic Allocation

RULE: Cannot use heap (no allocator)
WHY: Deterministic memory, no OOM
RUST: heapless::Vec<T, N>, arrays

Interrupt Safety

RULE: Shared state must be interrupt-safe
WHY: ISR can preempt at any time
RUST: Mutex<RefCell<T>> + critical section

Hardware Ownership

RULE: Peripherals must have clear ownership
WHY: Prevent conflicting access
RUST: HAL takes ownership, singletons
