Expand description

| An in-memory indexed chain of blocks. |

Implementations§

source§

impl Chain

source

pub fn genesis(&self) -> Option<Arc<BlockIndex>>

| Returns the index entry for the genesis | block of this chain, or nullptr if none. |

source

pub fn set_tip(&mut self, pindex: Option<Arc<BlockIndex>>)

| Set/initialize a chain with a given | tip. |

source

pub fn find_fork( &self, pindex: Option<Arc<BlockIndex>> ) -> Option<Arc<BlockIndex>>

| Find the last common block between this | chain and a block index entry. |

source

pub fn find_earliest_at_least( &self, n_time: i64, height: i32 ) -> Option<Arc<BlockIndex>>

| Find the earliest block with timestamp | equal or greater than the given time | and height equal or greater than the | given height. |

Trait Implementations§

source§

impl ChainHeight for Chain

source§

fn height(&self) -> Option<usize>

| Return the maximal height in the chain. | Is equal to chain.Tip() ? chain.Tip()->nHeight | : -1. |

source§

impl ChainNext for Chain

source§

fn next(&self, pindex: Option<Arc<BlockIndex>>) -> Option<Arc<BlockIndex>>

| Find the successor of a block in this | chain, or nullptr if the given index | is not found or is the tip. |

source§

impl Contains<Arc<BlockIndex>> for Chain

source§

fn contains(&self, pindex: Option<Arc<BlockIndex>>) -> bool

| Efficiently check whether a block is | present in this chain. |

source§

impl GetLocator<Arc<BlockIndex>> for Chain

source§

fn get_locator(&self, pindex: Option<Arc<BlockIndex>>) -> Self::LocatorType

| Return a CBlockLocator that refers | to a block in this chain (by default the | tip). |

§

type LocatorType = BlockLocator

source§

impl Index<i32> for Chain

source§

fn index(&self, n_height: i32) -> &Self::Output

| Returns the index entry at a particular | height in this chain, or nullptr if no | such height exists. |

§

type Output = Option<Arc<BlockIndex>>

The returned type after indexing.
source§

impl Tip for Chain

source§

fn tip(&self) -> Option<Arc<BlockIndex>>

| Returns the index entry for the tip of | this chain, or nullptr if none. |
