Implementations

impl HeaderChain

pub fn open_bootstrap( cache_dir: &Path, bootstrap: HeaderBootstrap, ) -> Result<Self, Error>

Open a strict checkpoint-relative view. Context was authenticated by HeaderBootstrap::new before any cache access. Its cache namespace is separate from legacy pinned-successor caches and binds height as well as chain and anchor hash. Ancestors never enter the selected index.
