Struct ps_datachunk::owned::OwnedDataChunk

pub struct OwnedDataChunk { /* private fields */ }

represents an owned chunk of data

Implementations

impl OwnedDataChunk

pub fn data_ref(&self) -> &[u8]

pub fn hash_ref(&self) -> &[u8]

pub fn hash(&self) -> Arc<Hash>

pub fn from_parts(data: Vec<u8>, hash: Arc<Hash>) -> Self

Creates an OwnedDataChunk from its constituent parts

Safety

• hash must be the hash of data
• use from_data() if you cannot ensure this

pub fn from_data(data: Vec<u8>) -> Self

calculates the hash of data and returns an OwnedDataChunk

pub fn from_data_ref_and_hash(data: &[u8], hash: Arc<Hash>) -> Self

creates an OwnedDataChunk with given data and hash

pub fn from_data_ref(data: &[u8]) -> Self

creates an OwnedDataChunk with given data

pub fn serialize_into(self) -> Vec<u8>

converts this OwnedDataChunk into a Vec<u8>

• extends self.hash
• returns self.data

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

serializes this OwnedDataChunk into a newly allocated Vec<u8>

• allocated a new Vec<u8>
• copies self.data into the new Vec<u8>
• copies self.hash into the new Vec<u8>
• returns the new Vec<u8>

pub fn deserialize_from(data: Vec<u8>) -> Result<Self>

• converts a Vec<u8> into an OwnedDataChunk
• performs hash validation

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

Copies data into a new Vec<u8> and deserializes it into an OwnedDataChunk.

pub fn decrypt_bytes( encrypted: &[u8], key: &[u8], compressor: &Compressor, ) -> Result<Self>

Decrypts into an OwnedDataChunk with the given key

• performs hash validation
• fails if key not correct

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

Decrypts an OwnedDataChunk with the given key.

• performs hash validation
• fails if key not correct

pub fn encrypt_serialized_bytes( bytes: &[u8], compressor: &Compressor, ) -> Result<EncryptedDataChunk>

Encrypts a serialized DataChunk.

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

Encrypts this DataChunk.

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

Encrypts this DataChunk.

• optimized by using self.data as the serialization buffer

impl Into<OwnedDataChunk> for &AlignedDataChunk

fn into(self) -> OwnedDataChunk

Converts this type into the (usually inferred) input type.

impl Ord for OwnedDataChunk

fn cmp(&self, other: &OwnedDataChunk) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for OwnedDataChunk

fn eq(&self, other: &OwnedDataChunk) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
