Struct AlignedVec

pub struct AlignedVec { /* private fields */ }

A Vec of bytes whose length is guaranteed to be aligned to 4 bytes. This makes certain operations cheaper in zk-context (namely, concatenation).

Implementations

impl AlignedVec

pub const ALIGNMENT: usize = 4usize

The length of the chunks of the aligned vector.

pub fn new(vector: Vec<u8>) -> Self

Creates a new AlignedVec whose length is aligned to AlignedVec::ALIGNMENT bytes.

pub fn extend(&mut self, other: &Self)

Extends self with the contents of the other AlignedVec.

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

Consumes self and returns the underlying Vec of bytes.

pub fn len(&self) -> usize

Returns the length in bytes of the prefix.

pub fn is_empty(&self) -> bool

Returns true if the prefix is empty, false otherwise.

Trait Implementations

impl AsRef<Vec<u8>> for AlignedVec

fn as_ref(&self) -> &Vec<u8>

Converts this type into a shared reference of the (usually inferred) input type.

impl BorshDeserialize for AlignedVec

where Vec<u8>: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for AlignedVec

where Vec<u8>: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for AlignedVec

fn clone(&self) -> AlignedVec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlignedVec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AlignedVec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AlignedVec

fn eq(&self, other: &AlignedVec) -> 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.

impl Serialize for AlignedVec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
