Struct Tip5

pub struct Tip5 {
    pub state: [BFieldElement; 16],
}

Fields

state: [BFieldElement; 16]

Implementations

impl Tip5

pub const fn new(domain: Domain) -> Tip5

pub const fn offset_fermat_cube_map(x: u16) -> u16

pub fn permutation(&mut self)

pub fn trace(&mut self) -> [[BFieldElement; 16]; 6]

Functionally equivalent to permutation. Returns the trace of applying the permutation; that is, the initial state of the sponge as well as its state after each round.

pub fn hash_10(input: &[BFieldElement; 10]) -> [BFieldElement; 5]

hash_10 Hash 10 elements, or two digests. There is no padding because the input length is fixed.

Trait Implementations

impl AlgebraicHasher for Tip5

fn hash_pair(left: Digest, right: Digest) -> Digest

2-to-1 hashing

fn hash<T>(value: &T) -> Digest

where T: BFieldCodec,

Thin wrapper around hash_varlen.

fn hash_varlen(input: &[BFieldElement]) -> Digest

Hash a variable-length sequence of BFieldElement.

fn sample_indices(&mut self, upper_bound: u32, num_indices: usize) -> Vec<u32>

Produce num_indices random integer values in the range [0, upper_bound). The upper_bound must be a power of 2.

fn sample_scalars(&mut self, num_elements: usize) -> Vec<XFieldElement>

Produce num_elements random XFieldElement values.

impl<'arbitrary> Arbitrary<'arbitrary> for Tip5

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Tip5, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Tip5, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl BFieldCodec for Tip5

type Error = Tip5BFieldDecodingError

fn decode( sequence: &[BFieldElement], ) -> Result<Box<Tip5>, <Tip5 as BFieldCodec>::Error>

fn encode(&self) -> Vec<BFieldElement>

fn static_length() -> Option<usize>

Returns the length in number of BFieldElements if it is known at compile-time. Otherwise, None.

impl Clone for Tip5

fn clone(&self) -> Tip5

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tip5

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

Formats the value using the given formatter.

impl Default for Tip5

fn default() -> Tip5

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Tip5

fn deserialize<__D>( __deserializer: __D, ) -> Result<Tip5, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl GetSize for Tip5

fn get_heap_size(&self) -> usize

Determines how many bytes this object occupies inside the heap.

fn get_stack_size() -> usize

Determines how may bytes this object occupies inside the stack.

fn get_size(&self) -> usize

Determines the total size of the object.

impl PartialEq for Tip5

fn eq(&self, other: &Tip5) -> 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 Tip5

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sponge for Tip5

const RATE: usize = 10usize

fn init() -> Tip5

fn absorb(&mut self, input: [BFieldElement; 10])

fn squeeze(&mut self) -> [BFieldElement; 10]

fn pad_and_absorb_all(&mut self, input: &[BFieldElement])
