Struct ContentDenylist 

pub struct ContentDenylist { /* private fields */ }

The union of the operator’s local denylist and the on-chain origin blacklist, as consulted by the delivery path.

Implementations

impl ContentDenylist

pub fn new(content: &ResolvedContent) -> Self

Build from resolved config, with an empty on-chain set — the watcher fills that in once its bootstrap enumeration completes (#1504).

pub fn empty() -> Self

An empty deny-set, for tests and for wiring paths with no [content] section resolved yet.

pub fn is_origin_denied(&self, addr: &Address) -> bool

Is this address denied as a channel funder, by either source?

pub fn set_local_origins(&self, content: &ResolvedContent) -> usize

Swap in the origin half of a freshly resolved [content] section, returning the new entry count for the reload log line.

Touches only the local slot — the on-chain set is the watcher’s, and the hash half is the cache engine’s.

pub fn set_chain_origins(&self, origins: HashSet<Address>)

Replace the on-chain origin set wholesale — the watcher’s boot seed from the enumerated address union, and its periodic re-enumeration refresh.

The union is the origin ∪ operator deny set read from ContentBlacklist.blacklistedAddresses, liveness-filtered by isOriginBlacklisted || isOperatorBlacklisted (see decdn-node::blacklist_watcher). It is rebuilt from chain each boot, so there is no durable projection to reload.

pub fn apply_chain_origin(&self, addr: Address, blacklisted: bool) -> bool

Apply a single OriginBlacklistUpdated event.

Read-modify-write rather than an in-place mutation, because ArcSwap has no such thing. Origin events are rare (a governance action), so the clone is irrelevant next to keeping reads lock-free; a RwLock would trade that for a write that is still rare. Returns whether the set actually changed, so callers can skip logging a no-op replay — the watcher re-scans a block range after a restart and will re-deliver events it has already applied.

pub fn chain_origin_count(&self) -> usize

Number of on-chain blacklisted origins currently tracked. For telemetry and the admin surface.
