Struct Chain 

pub struct Chain<'a> { /* private fields */ }

Represents a chain instance for querying and traversal.

Implementations

impl<'a> Chain<'a>

pub fn tip(&self) -> BlockTreeEntry<'a>

Returns the tip (highest block) of the active chain.

pub fn genesis(&self) -> BlockTreeEntry<'a>

Returns the genesis block (height 0) of the chain.

pub fn at_height(&self, height: usize) -> Option<BlockTreeEntry<'a>>

Returns the block at the specified height, if it exists.

pub fn contains(&self, entry: &BlockTreeEntry<'a>) -> bool

Checks if the given block entry is part of the active chain.

pub fn iter(&self) -> ChainIterator<'a>

Returns an iterator over all blocks from genesis to tip.

pub fn height(&self) -> i32

fn clone(&self) -> Self

Returns a duplicate of the value.

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