Struct flow_sdk::entities::BlockHeader

pub struct BlockHeader {
    pub id: Box<[u8]>,
    pub parent_id: Box<[u8]>,
    pub height: u64,
    pub timestamp: Timestamp,
}

A block header is a summary of a block and contains only the block ID, height, and parent block ID.

Fields

id: Box<[u8]>

SHA3-256 hash of the entire block payload

parent_id: Box<[u8]>

ID of the previous block in the chain

height: u64

Height of the block in the chain

timestamp: Timestamp

Timestamp of when the proposer claims it constructed the block.

NOTE: It is included by the proposer, there are no guarantees on how much the time stamp can deviate from the true time the block was published. Consider observing blocks’ status changes yourself to get a more reliable value.

Trait Implementations

impl Debug for BlockHeader

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

Formats the value using the given formatter.

impl<'de> Decodable<'de> for BlockHeader where
    Self: Default, 

type Wire = LengthDelimitedWire

fn decode<B: Buf>(d: &mut Deserializer<'de, B>) -> Result<Self>

fn merge(&mut self, other: Self)

If this is a message, call merge() on all fields, if this is repeated, extend this with the elements of other. for all other types simply overwrite this with other, which is the default.

fn merge_from<B>(
    &mut self,
    deserializer: &mut Deserializer<'de, B>
) -> Result<(), DecodingError> where
    B: Buf, 

impl<'de> DecodableMessage<'de> for BlockHeader

type Tag = u8

How big the tag message gets. This is an unsigned varint.

fn decode_field<B: Buf>(
    &mut self,
    d: &mut Deserializer<'de, B>,
    tag: Self::Tag
) -> Result<()>

Decodes a field with the given tag.

fn decode<B>(
    deserializer: &mut Deserializer<'de, B>
) -> Result<Self, DecodingError> where
    B: Buf,
    Self: Default, 

impl Default for BlockHeader

fn default() -> BlockHeader

Returns the “default value” for a type.

impl PartialEq<BlockHeader> for BlockHeader

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

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

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

This method tests for !=.
