Struct BestChain

pub struct BestChain {
    pub best_block: BlockHash,
    pub depth: u32,
    pub validation_index: BlockHash,
    pub alternative_tips: Vec<BlockHash>,
    pub assume_valid_index: u32,
}

Internal representation of the chain we are in

Fields

best_block: BlockHash

Hash of the last block in the chain we believe has more work on

depth: u32

How many blocks are pilled on this chain?

validation_index: BlockHash

We actually validated blocks up to this point

alternative_tips: Vec<BlockHash>

Blockchains are not fast-forward only, they might have “forks”, sometimes it’s useful to keep track of them, in case they become the best one. This keeps track of some tips we know about, but are not the best one. We don’t keep tips that are too deep or has too little work if compared to our best one

assume_valid_index: u32

Saves the height occupied by the assume valid block

Trait Implementations

impl Clone for BestChain

fn clone(&self) -> BestChain

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BestChain

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

Formats the value using the given formatter.

impl Decodable for BestChain

fn consensus_decode<R: Read + ?Sized>(reader: &mut R) -> Result<Self, Error>

Decode an object with a well-defined format.

fn consensus_decode_from_finite_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + ?Sized,

Decode Self from a size-limited reader.

impl Encodable for BestChain

fn consensus_encode<W: Write + ?Sized>(&self, writer: &mut W) -> Result<usize>

Encodes an object with a well-defined format.

impl From<(BlockHash, u32)> for BestChain

fn from((best_block, depth): (BlockHash, u32)) -> Self

Converts to this type from the input type.

impl PartialEq for BestChain

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