Struct ReorgWindow 

pub struct ReorgWindow { /* private fields */ }

Sliding window of block hashes used during reorg detection.

Implementations

impl ReorgWindow

pub fn new(limit: usize) -> Self

Creates a new reorg window with the specified size limit.

The limit is clamped to a minimum of 1.

pub fn len(&self) -> usize

Returns the number of blocks currently stored in the window.

pub fn limit(&self) -> usize

Returns the configured size limit of the window.

pub fn is_empty(&self) -> bool

Returns true if the window contains no blocks.

pub fn push(&mut self, height: u64, hash: BlockHash)

Adds a block to the window, evicting the oldest entry if the limit is reached.

pub fn find_hash(&self, hash: &BlockHash) -> Option<u64>

Searches for a block hash in the window and returns its height if found.

The search starts from the most recent block.

pub fn clear(&mut self)

Removes all blocks from the window.

pub fn truncate_after(&mut self, height: u64)

Removes entries whose height is greater than the provided value while keeping the older portion of the window intact.

pub fn iter(&self) -> impl Iterator<Item = &(u64, BlockHash)>

Returns an iterator over the blocks in the window.

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

Performs copy-assignment from source.
