Create an independent copy of a byte buffer
C: Allocate the exact byte length and copy only after checking the result.
C✓ Tested
Grow an allocation without losing it on failure
C: Assign realloc to a temporary pointer so the original allocation remains available if growth fails.
C✓ Tested
Initialize a byte buffer to zero
C: memset initializes each byte to the chosen unsigned-char value.
C✓ Tested
Move a collection out and leave an empty default
Move a collection out and leave an empty default in a complete Rust program using the standard library.
Rust✓ Tested
Read 16-bit values from a flash table
Arduino / C: pgm_read_word retrieves a complete word from program memory.
Arduino / C✓ Tested
Read a byte lookup table from flash
Arduino / C: PROGMEM tables require the AVR program-memory access functions.
Arduino / C✓ Tested
Read and total a flash lookup table
Arduino / C: Array size can be computed at compile time even for a flash-resident table.
Arduino / C✓ Tested
Reject an unsupported settings version
Arduino / C: A version byte lets firmware fall back when stored settings use another format.
Arduino / C✓ Tested
Replace a value and keep the old value
Replace a value and keep the old value in a complete Rust program using the standard library.
Rust✓ Tested
Represent a set with empty structs
Represent a set with empty structs using a complete Go program with explicit sample inputs.
Go✓ Tested
Store a bounded null-terminated text setting
Arduino / C: Write a fixed buffer and explicitly terminate the retrieved copy.
Arduino / C✓ Tested
Store a compact configuration record
Arduino / C: Save a struct and retrieve it with the same field layout.
