Struct BlockHeader 

pub struct BlockHeader {
    pub checksum: u32,
    pub magic: [u8; 4],
}

8-byte header at the beginning of each block.

A block does not identify its own size, so any reference to a block must also include the block’s size.

Fields

checksum: u32

32-bit crc32c checksum of the remainder of the block.

magic: [u8; 4]

Magic number. Magic numbers begin with LF, which stands for “layer file”.
