Struct BlockIndex

Source 
pub struct BlockIndex { /* private fields */ }
Expand description

A block index that is tied to a specific ChainstateManager.

Internally the ChainstateManager keeps an in-memory of the current block tree once it is loaded. The BlockIndex points to an entry in this tree. It is only valid as long as the ChainstateManager it was retrieved from remains in scope.

Implementations§

Source§

impl BlockIndex

Source

pub fn prev(self) -> Result<BlockIndex, KernelError>

Move to the previous entry in the block tree. E.g. from height n to height n-1.

Source

pub fn height(&self) -> i32

Get the current height associated with this BlockIndex.

Source

pub fn block_hash(&self) -> BlockHash

Get the current block hash associated with this BlockIndex.
