pub const MAGIC: u32 = 0xFD2FB528;Expand description
The “magic number” identifying the start of a data frame.
As per the RFC:
The magic number was selected to be less probable to find at the beginning of an arbitrary file. It avoids trivial patterns (0x00, 0xFF, repeated bytes, increasing bytes, etc.), contains byte values outside of the ASCII range, and doesn’t map into UTF-8 space, all of which reduce the likelihood of its appearance at the top of a text file.
