Function fetch_new_blocks

async fn fetch_new_blocks(
    db: &Database,

    current_height: u32,
    finality_depth: u32,
) -> Result<Option<Vec<BlockInfo>>, BridgeError>

Fetches the next block from Bitcoin, if it exists. Will also fetch previous blocks if the parent is missing, and give an error if the number of reorged blocks is greater than the finality depth.

Parameters

• current_height: The height of the current tip in the database.

Returns

• None - If no new block is available.
• Vec<BlockInfo> - If new blocks are found.
• BridgeError - If the number of reorged blocks is greater than the finality depth or db/rpc errors.
