Implementations

impl OwnedDataChunk

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, PsDataChunkError>

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

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

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, PsDataChunkError>

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, PsDataChunkError>

Decrypts an OwnedDataChunk with the given key.

• performs hash validation
• fails if key not correct

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

Encrypts a serialized DataChunk.

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.

• optimized by using self.data as the serialization buffer

Trait Implementations

impl Archive for OwnedDataChunk

where [u8; 50]: Archive, Vec<u8>: Archive,

type Archived = ArchivedOwnedDataChunk

The archived representation of this type.

type Resolver = OwnedDataChunkResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for OwnedDataChunk

fn clone(&self) -> OwnedDataChunk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedDataChunk

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

Formats the value using the given formatter.

impl From<&OwnedDataChunk> for AlignedDataChunk

fn from(value: &OwnedDataChunk) -> Self

Converts to this type from the input type.

impl Hash for OwnedDataChunk

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'lt> Into<DataChunk<'lt>> for OwnedDataChunk

fn into(self) -> DataChunk<'lt>

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

impl Into<OwnedDataChunk> for AlignedDataChunk

fn into(self) -> OwnedDataChunk

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

impl<'lt> Into<OwnedDataChunk> for DataChunk<'lt>

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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for OwnedDataChunk

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for OwnedDataChunk

fn partial_cmp(&self, other: &OwnedDataChunk) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<__S: Fallible + ?Sized> Serialize<__S> for OwnedDataChunk

where [u8; 50]: Serialize<__S>, Vec<u8>: Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
