Struct btlib::crypto::merkle_stream::Sha2_256Node

pub struct Sha2_256Node(_);

A struct for storing SHA2 256 hashes in a MerkleTree.

Trait Implementations

impl Default for Sha2_256Node

fn default() -> Sha2_256Node

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Sha2_256Node

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

Deserialize this value from the given Serde deserializer.

impl MerkleNode for Sha2_256Node

const KIND: HashKind = HashKind::Sha2_256

The kind of hash algorithm that this HashData uses.

fn new<'a, I: Iterator<Item = &'a [u8]>>(parts: I) -> Result<Self>

Creates a new HashData instance by hashing the data produced by the given iterator and storing it in self.

fn combine<'a, I: Iterator<Item = &'a [u8]>>( &mut self, prefix: I, left: Option<&'a Self>, right: Option<&'a Self> ) -> Result<()>

Combines the hash data from the given children and prefix and stores it in self. It is an error for no children to be provided (though one or the other may be None).

fn assert_contains(&self, hash_data: Option<&[u8]>) -> Result<()>

Returns Ok(()) if self contains the given hash data, and Err(Error::HashCmpFailure) otherwise.

fn assert_contains_hash_of<'a, I: Iterator<Item = &'a [u8]>>( &self, parts: I ) -> Result<()>

Returns Ok(()) if self contains the hash of the given data. Otherwise, Err(Error::HashCmpFailure) is returned.

fn assert_parent_of<'a, I: Iterator<Item = &'a [u8]>>( &self, prefix: I, left: Option<&'a Self>, right: Option<&'a Self> ) -> Result<()>

Returns Ok(()) if the result of combining left and right is contained in self.

fn try_as_slice(&self) -> Result<&[u8]>

Attempts to borrow the data in this node as a slice.

fn digest<'a, I: Iterator<Item = &'a [u8]>>( dest: &mut [u8], parts: I ) -> Result<()>

Computes the hash of the data produced by the given iterator and writes it to the given slice.

impl Serialize for Sha2_256Node

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

Serialize this value into the given Serde serializer.
