Struct V1Header 

pub struct V1Header {
    pub compression: BlockCompression,
    pub original_size: u32,
    pub compressed_size: u32,
    pub checksum: u32,
}

V1 block header (original format, 17 bytes)

Layout:

• bytes 0-3: magic “TBLK”
• byte 4: compression type
• bytes 5-8: original size (u32 LE)
• bytes 9-12: compressed size (u32 LE)
• bytes 13-16: CRC32 checksum (u32 LE)

Fields

compression: BlockCompression

original_size: u32

compressed_size: u32

checksum: u32
