💅 vector-copy (3scm) — the Scheme Programmer's Manual cutie 💅

okay bestie, welcome to the vector-copy(3scm) page from the Scheme Programmer's Manual — it’s giving “copy that vector” and honestly? iconic. Let’s get into it. 🦋✨

---

✨ NAME ✨

vector-copy — copy a vector 💖

---

📚 LIBRARY 📚

(import (scheme base)) ;R7RS

yep, that’s the R7RS import, bestie. 🎀

---

🌸 SYNOPSIS 🌸

(vector-copy vector)
(vector-copy vector start)
(vector-copy vector start end)

---

🫶 DESCRIPTION 🫶

Returns a newly allocated copy of the elements of the given vector between start and end. 🔥

The elements of the new vector are the same — in the sense of eqv?(3scm) — as the elements of the old vector. no cap, that’s the whole vibe. 💜

---

👑 RETURN VALUES 👑

Returns a single value: a new vector object. periodt. 💅

---

🍓 EXAMPLES 🍓

(define a #(1 8 2 8))      ; a may be immutable
(define b (vector-copy a)) ; b is mutable
(vector-set! b 0 3)
b => #(3 8 2 8)

(vector-copy b 1 3)  =>  #(8 2)

look at b thriving and mutable — we love to see it. 😭💖

---

🧚 COMPATIBILITY 🧚

There’s an equivalent procedure in SRFI-43. yep, the SRFI-43 girlies are covered too. 🌈

---

💀 ERRORS 💀

It is an error if the wrong number of arguments was passed or an argument was outside its domain. 🚨

R7RS implementations may:

• signal an error,
• extend the procedure’s domain of definition to include such arguments,
• or fail catastrophically.

that last one is not a vibe, bestie — proceed with caution. 🙈💀

🎀 HISTORY 🎀

The first RnRS revision with this procedure is R7RS, which took it from SRFI-43. history lesson slay. 💅📖
