Struct Policy 

pub struct Policy { /* private fields */ }

The whole allowlist. Parsing validates every key up front, so a malformed peers.json fails loudly at startup rather than silently at message time.

Implementations

impl Policy

pub fn load(path: &Path) -> Result<Self>

pub fn parse(raw: &str) -> Result<Self>

pub fn peer(&self, id: AgentId) -> Option<&Peer>

Look up an authenticated sender. None ⇒ not on the allowlist ⇒ drop.

pub fn resolve(&self, petname: &str) -> Result<AgentId>

Resolve a petname to a key for outbound sends.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn peers(&self) -> &[Peer]

All peers, for listing.

pub fn add(&mut self, petname: &str, key_b64: &str) -> Result<()>

Admit a peer (or no-op if the same petname→key pair is already present). Rejects a petname already bound to a different key, or a key already held under a different petname — either would make the authenticated sender lookup ambiguous, exactly as Policy::parse guards against.

pub fn remove(&mut self, petname: &str) -> bool

Remove a peer by petname; returns whether one was removed.

pub fn to_json(&self) -> Result<String>

Serialize back to the peers.json object form.

pub fn save(&self, path: &Path) -> Result<()>

Persist the current allowlist to path.
