Struct Block 

pub struct Block {
    pub header: BlockHeader,
    pub data: Bytes,
}

A storage block containing header and data.

Fields

header: BlockHeader

data: Bytes

Implementations

impl Block

pub fn new(block_id: BlockId, block_type: BlockType, data: Bytes) -> Self

Create a new block with the given data.

pub fn empty(block_id: BlockId, block_type: BlockType) -> Self

Create an empty block.

pub fn verify_checksum(&self) -> bool

Verify the block’s checksum.

pub fn update_checksum(&mut self)

Update the checksum after modifying data.

pub fn compress(&mut self, compression: CompressionType) -> Result<()>

Compress the block data using the specified algorithm.

pub fn decompress(&mut self) -> Result<()>

Decompress the block data.

pub fn encrypt(&mut self, encryption: EncryptionType) -> Result<()>

Encrypt the block data using the specified algorithm. Note: Encryption should be applied after compression for better compression ratios.

pub fn decrypt(&mut self) -> Result<()>

Decrypt the block data. Note: Decryption should be applied before decompression.

pub fn to_bytes(&self) -> Result<Bytes>

Serialize the entire block to bytes.

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

Deserialize a block from bytes.

pub fn size(&self) -> usize

Get the total size of the block in bytes.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Block

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
