Struct exocore_chain::chain::directory::DirectoryChainStore

pub struct DirectoryChainStore { /* fields omitted */ }

Directory based chain persistence. The chain is split in segments with configurable maximum size. This maximum size allows using mmap on 32bit systems by preventing segments from growing over 4gb.
