Struct RevocationLog 

pub struct RevocationLog { /* private fields */ }

The ordered, signed nodes of one user’s revocation log.

Implementations

impl RevocationLog

pub fn genesis(user: &UserKey) -> Result<Self>

A new log owned by user: just the signed genesis node.

Errors

MeshError::Encoding if the node cannot be encoded.

pub fn append(&mut self, user: &UserKey, entry: RevocationEntry) -> Result<()>

Append entry, signed by user, parented on the current head.

Errors

MeshError::RevocationState if user does not own this log, the log is not valid, entry is a Genesis, or a Generation does not exceed the current one. Nothing is appended on error.

pub fn verify(&self) -> Result<RevocationState>

Check the whole log and fold it into a RevocationState.

Fail-closed: genesis first, each parent is the previous id, every signature verifies under the genesis user, generations strictly increase.

Errors

MeshError::RevocationState for a structural break; MeshError::BadSignature for a signature that does not verify.

pub fn extends(&self, seen: &Seen) -> Result<()>

Refuse a log that is shorter than what the consumer seen, or whose node at that position is not the head they saw (a fork). A log that is itself invalid, or belongs to another user, is refused too.

Errors

MeshError::RevocationState on rollback, fork, wrong user, or empty seen.
