Struct BlockId 

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

Available on crate feature block only.

A block identifier, the BLAKE2b-256 hash of the block bytes. See https://www.blake2.net/ for more information.

Implementations

impl BlockId

pub const LENGTH: usize = 32

The length of a [$ty].

pub fn new(bytes: [u8; 32]) -> Self

Creates a new [$ty].

pub fn null() -> Self

Creates a null [$ty].

pub fn is_null(&self) -> bool

Checks if the [$ty] is null.

Trait Implementations

impl<__AsRefT: ?Sized> AsRef<__AsRefT> for BlockId

where [u8; 32]: AsRef<__AsRefT>,

fn as_ref(&self) -> &__AsRefT

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

impl Clone for BlockId

fn clone(&self) -> BlockId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockId

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

Formats the value using the given formatter.

impl Deref for BlockId

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for BlockId

fn deserialize<D>(deserializer: D) -> Result<BlockId, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockId

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

Formats the value using the given formatter.

impl From<[u8; 32]> for BlockId

fn from(original: [u8; 32]) -> BlockId

Converts to this type from the input type.

impl FromStr for BlockId

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 BlockId

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 Ord for BlockId

fn cmp(&self, other: &BlockId) -> 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 Packable for BlockId

type UnpackError = <[u8; 32] as Packable>::UnpackError

The error type that can be returned if some semantic error occurs while unpacking.

type UnpackVisitor = <[u8; 32] as Packable>::UnpackVisitor

FIXME: docs

fn pack<P: Packer>(&self, packer: &mut P) -> Result<(), P::Error>

Packs this value into the given Packer.

fn unpack<U: Unpacker, const VERIFY: bool>( unpacker: &mut U, visitor: &Self::UnpackVisitor, ) -> Result<Self, UnpackError<Self::UnpackError, U::Error>>

Unpacks this value from the given Unpacker. The VERIFY generic parameter can be used to skip additional syntactic checks.

impl PartialEq for BlockId

fn eq(&self, other: &BlockId) -> 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 BlockId

fn partial_cmp(&self, other: &BlockId) -> 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 BlockId

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
