Implementations

impl BlockRef

Fixed size of BlockRef when serialized (21 bytes) Layout: offset(8) + compressed_len(4) + original_len(4) + compression(1) + checksum(4)

pub const SERIALIZED_SIZE: usize = 21

Fixed serialization size

pub fn to_bytes(&self) -> Result<[u8; 21]>

Serialize to fixed-layout bytes (Task 5: returns Result)

pub fn from_bytes(data: &[u8]) -> Result<Self>

Deserialize from fixed-layout bytes
