Trait Implementations

impl<'a> Arbitrary<'a> for BlockHash

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

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

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

impl AsRef<[u8]> for BlockHash

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<[u8; 32]> for BlockHash

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<[u8]> for BlockHash

fn borrow(&self) -> &[u8]

Immutably borrows from an owned value.

impl Borrow<[u8; 32]> for BlockHash

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

Immutably borrows from an owned value.

impl Clone for BlockHash

fn clone(&self) -> BlockHash

Returns a duplicate 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 Decodable for BlockHash

type Decoder = BlockHashDecoder

Associated decoder for the type.

fn decoder() -> Self::Decoder

Constructs a “default decoder” for the type.

Available on crate feature alloc only.

fn from(block: Block) -> Self

Converts to this type from the input type.

impl From<Header> for BlockHash

fn from(header: Header) -> Self

Converts to this type from the input type.

impl FromStr for BlockHash

Available on crate feature hex only.

type Err = DecodeFixedLengthBytesError

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 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 LowerHex for BlockHash

Available on crate feature hex only.

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

Formats the value using the given formatter.

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.

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
