Struct casper_hashing::ChunkWithProof

pub struct ChunkWithProof { /* private fields */ }

Represents a chunk of data with attached proof.

Implementations

impl ChunkWithProof

pub const CHUNK_SIZE_BYTES: usize = 8_388_608usize

8 MiB

pub fn new(data: &[u8], index: u64) -> Result<Self, MerkleConstructionError>

Constructs the ChunkWithProof that contains the chunk of data with the appropriate index and the cryptographic proof.

Empty data is always represented as single, empty chunk and not as zero chunks.

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

Get a reference to the ChunkWithProof’s chunk.

pub fn into_chunk(self) -> Bytes

Convert a chunk with proof into the underlying chunk.

pub fn proof(&self) -> &IndexedMerkleProof

Returns the IndexedMerkleProof.

pub fn verify(&self) -> Result<(), ChunkWithProofVerificationError>

Verify the integrity of this chunk with indexed Merkle proof.

Trait Implementations

impl Clone for ChunkWithProof

fn clone(&self) -> ChunkWithProof

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for ChunkWithProof

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for ChunkWithProof

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChunkWithProof

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

Deserialize this value from the given Serde deserializer.

impl FromBytes for ChunkWithProof

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8, Global>) -> Result<(Self, Vec<u8, Global>), Error>

Deserializes the Vec<u8> into Self.

impl JsonSchema for ChunkWithProof

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq<ChunkWithProof> for ChunkWithProof

fn eq(&self, other: &ChunkWithProof) -> 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 Serialize for ChunkWithProof

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

Serialize this value into the given Serde serializer.

impl ToBytes for ChunkWithProof

fn write_bytes(&self, buf: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

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

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8, Global>, Error>where Self: Sized,

Consumes self and serializes to a Vec<u8>.
