Pattern for string with size?

[danielniccoli]

Hi,

I have the following data which translates to a string.

04 62 61 73 65

The first byte gives the length of the string and then you have the string.

I have the following pattern that works:

u8 len @ 0x0a;
char string[len] @ 0x0b;

I wonder if there's maybe a better way to do this?

Hello, yes there is a better way. Check out the standard library type: std::string::SizedString from the type.magic library. In this case you'd use it like this:

import type.magic;

std::string::SizedString<u8> string @ 0x0a;
