Struct casper_node::types::Block

pub struct Block { /* fields omitted */ }

A proto-block after execution, with the resulting post-state-hash. This is the core component of the Casper linear blockchain.

Implementations

impl Block

pub fn hash(&self) -> &BlockHash

The hash of this block's header.

pub fn deploy_hashes(&self) -> &Vec<DeployHash>

The deploy hashes included in this block.

pub fn height(&self) -> u64

The height of a block.

pub fn proofs(&self) -> &BTreeMap<PublicKey, Signature>

Provide proofs for an OpenRPC compatible representation.

pub fn verify(&self) -> Result<(), BlockValidationError>

Check the integrity of a block by hashing its body and header

Trait Implementations

impl Clone for Block

pub fn clone(&self) -> Block

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for Block

pub const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

pub const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

pub fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for Block

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Block

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

Deserialize this value from the given Serde deserializer.

impl Display for Block

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

Formats the value using the given formatter.

impl DocExample for Block

pub fn doc_example() -> &'static Self

Generates a hardcoded example of Self.

impl Eq for Block

impl From<Block> for JsonBlock

pub fn from(block: Block) -> Self

Performs the conversion.

impl From<JsonBlock> for Block

pub fn from(block: JsonBlock) -> Self

Performs the conversion.

impl FromBytes for Block

pub fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

pub fn from_vec(
    bytes: Vec<u8, Global>
) -> Result<(Self, Vec<u8, Global>), Error>

Deserializes the Vec<u8> into Self.

impl Hash for Block

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Item for Block

type Id = BlockHash

The type of ID of the item.

pub const TAG: Tag

The tag representing the type of the item.

pub const ID_IS_COMPLETE_ITEM: bool

Whether the item's ID is the complete item or not.

pub fn id(&self) -> Self::Id

The ID of the specific item.

impl Ord for Block

pub fn cmp(&self, other: &Block) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Block> for Block

pub fn eq(&self, other: &Block) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Block) -> bool

This method tests for !=.

impl PartialOrd<Block> for Block

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Block

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

Serialize this value into the given Serde serializer.

impl StructuralEq for Block

impl StructuralPartialEq for Block

impl ToBytes for Block

pub fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

pub 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.

pub fn into_bytes(self) -> Result<Vec<u8, Global>, Error>

Consumes self and serializes to a Vec<u8>.
