Struct ChainHash 

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

The uniquely identifying hash of the target blockchain.

Implementations

impl ChainHash

pub fn as_ptr(&self) -> *const u8

Converts the object to a raw pointer

pub fn as_mut_ptr(&mut self) -> *mut u8

Converts the object to a mutable raw pointer

pub fn len(&self) -> usize

Returns the length of the object as an array

pub fn is_empty(&self) -> bool

Returns whether the object, as an array, is empty. Always false.

pub fn as_bytes(&self) -> &[u8; 32]

Returns the underlying bytes.

pub fn to_bytes(self) -> [u8; 32]

Returns the underlying bytes.

pub fn into_bytes(self) -> [u8; 32]

Returns the underlying bytes.

impl ChainHash

pub fn using_genesis_block(network: Network) -> Self

Returns the hash of the network genesis block for use as a chain hash.

See BOLT 0 for specification.

impl<'a> From<&'a [u8]> for ChainHash

fn from(data: &'a [u8]) -> ChainHash

Converts to this type from the input type.

where I: Iterator<Item = Result<u8, Error>> + ExactSizeIterator + DoubleEndedIterator,

Produces an object from a byte iterator.

fn from_hex(s: &str) -> Result<Self, Error>

Produces an object from a hex string.

impl FromStr for ChainHash

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ChainHash

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<I> Index<I> for ChainHash

where [u8]: Index<I>,

type Output = <[u8] as Index<I>>::Output

The returned type after indexing.

fn index(&self, index: I) -> &Self::Output

Performs the indexing (container[index]) operation.

impl LowerHex for ChainHash

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

Formats the value using the given formatter.

impl Ord for ChainHash

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

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

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.
