Struct StatusCache 

pub struct StatusCache { /* private fields */ }

Per-line cache of the newest verified document, under the varve root.

Implementations

impl StatusCache

pub fn at_root(root: &Path) -> Self

pub fn update( &self, line: &Line, envelope: &[u8], parsed: &LineStatus, ) -> Result<(), LineStatusError>

Store a VERIFIED envelope for its line, refusing counter regressions.

pub fn envelope_bytes( &self, line: &Line, ) -> Result<Option<Vec<u8>>, LineStatusError>

The cached envelope bytes for a line, unparsed, if any.

Used by archive to carry the baseline across an air gap (varve#77). Deliberately opaque: the caller re-attaches the bytes verbatim, and the far side re-verifies against its own trust root — archiving must not become a place where a document is re-signed or re-shaped.

pub fn load( &self, line: &Line, root_public_key: &[u8], ) -> Result<Option<LineStatus>, LineStatusError>

Load and re-verify the cached envelope for a line.
