Struct BlockHash

pub struct BlockHash(/* private fields */);

A cryptographic hash uniquely identifying a Block.

Note

The type of this field is currently the same for all versions of blocks, and furthermore it is always a hash over the block’s header. However, how the hash is calculated can be different.

There are two separate functions to allow for validation of the block given the different hash mechanisms: validate_block_hashes_v1 and validate_block_hashes_v2.

Implementations

impl BlockHash

pub fn new(digest: Digest) -> Self

Returns a new BlockHash.

pub fn inner(&self) -> Digest

Returns a copy of the wrapped Digest.

Trait Implementations

impl Clone for BlockHash

fn clone(&self) -> BlockHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHash

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

Formats the value using the given formatter.

impl Default for BlockHash

fn default() -> BlockHash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockHash

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockHash

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

Formats the value using the given formatter.

impl Hash for BlockHash

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 JsonSchema for BlockHash

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 Ord for BlockHash

fn cmp(&self, other: &BlockHash) -> 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,

Restrict a value to a certain interval.

impl PartialEq for BlockHash

fn eq(&self, other: &BlockHash) -> 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 PartialOrd for BlockHash

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for BlockHash

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 BlockHash

fn write_bytes(&self, buffer: &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>, Error>

where Self: Sized,

Consumes self and serializes to a Vec<u8>.
