00:00:06,570 --> 00:00:07,403
- Hello, again.

2
00:00:07,403 --> 00:00:09,150
Welcome to Lesson Seven.

3
00:00:09,150 --> 00:00:10,740
In this lesson, we're going to take a look

4
00:00:10,740 --> 00:00:13,440
at a concept called "borrowing,"
which is effectively

5
00:00:13,440 --> 00:00:15,420
where you take a reference to an object

6
00:00:15,420 --> 00:00:17,580
without claiming ownership.

7
00:00:17,580 --> 00:00:19,860
We'll begin with some simple
examples of borrowing,

8
00:00:19,860 --> 00:00:22,590
so you can understand the
concepts and the syntax.

9
00:00:22,590 --> 00:00:24,750
Then we discuss the Rust borrow checker,

10
00:00:24,750 --> 00:00:26,340
which is a part of the compiler

11
00:00:26,340 --> 00:00:30,270
that ensures you follow the
rules of borrowing correctly.

12
00:00:30,270 --> 00:00:31,710
After that, we'll take a look

13
00:00:31,710 --> 00:00:34,740
at string slices and array slices.

14
00:00:34,740 --> 00:00:36,420
A string slice is like a reference

15
00:00:36,420 --> 00:00:39,090
into an existing slice,
like a (indistinct),

16
00:00:39,090 --> 00:00:41,010
and an array slice is like a reference

17
00:00:41,010 --> 00:00:42,363
into an existing array.
