• DataChunk::Mbuf() is copied via .to_owned()

pub fn serialize(&self) -> Vec<u8>

Serializes this DataChunk into a new Vec<u8>.

pub fn decrypt( &self, key: &[u8], compressor: &Compressor, ) -> Result<Self, PsDataChunkError>

Decrypts this DataChunk with a given key.

pub fn encrypt( &self, compressor: &Compressor, ) -> Result<EncryptedDataChunk, PsDataChunkError>

Encrypts this DataChunk.

pub fn encrypt_mut( &mut self, compressor: &Compressor, ) -> Result<EncryptedDataChunk, PsDataChunkError>

Encrypts this DataChunk using self.data if owned.

pub fn guarantee_alignment<T>(self) -> DataChunk<'lt>
