00:00:06,080 --> 00:00:10,250
And then to wrap up this section, I want to talk about static lifetimes.

2
00:00:10,550 --> 00:00:16,880
When we give a reference, a static lifetime, the reference can live for the entire duration of the

3
00:00:16,880 --> 00:00:17,570
program.

4
00:00:18,420 --> 00:00:22,110
All string literals have a static lifetime.

5
00:00:22,110 --> 00:00:24,210
So let's see what this looks like real quick.

6
00:00:24,210 --> 00:00:36,000
So we're going to say let s of a reference with a static lifetime string slice equal.

7
00:00:37,350 --> 00:00:42,300
I have a static lifetime and it's valid.

8
00:00:42,390 --> 00:00:48,570
So when we give the string literal a static lifetime, the text of the string is stored directly in

9
00:00:48,570 --> 00:00:54,510
the program's binary, so it is always available, some will suggest, to use static lifetimes and error

10
00:00:54,510 --> 00:00:59,160
messages, but you will want to consider whether you want something to live that long or not.

11
00:00:59,960 --> 00:01:03,530
Most lifetime errors will result from dangling references.

12
00:01:03,530 --> 00:01:09,320
So it is better to just fix the problem the correct way than to assign it a static lifetime.
