Struct Verifier 

pub struct Verifier { /* private fields */ }

Verifies a log’s entries in sequence against the signer’s public identity.

A verifier checks each entry’s index, its link to the previous entry, and its signature, advancing only on success. Feed it entries oldest first; the first failure is the point the log was tampered with.

Implementations

impl Verifier

pub fn new(public: PublicIdentity) -> Self

Creates a verifier for a log signed by public, starting at the first entry.

Arguments

• public - the public identity expected to have signed the log.

Returns

A verifier positioned at the first entry.

pub fn check(&mut self, entry: &Entry) -> Result<()>

Verifies the next entry in sequence, advancing the verifier on success.

Arguments

• entry - the next entry in the log.

Returns

Ok(()) if the entry is in sequence, correctly chained, and authentically signed.

Errors

Returns Error::Auth if the entry is out of sequence, its chain link is wrong, or its signature does not verify.
