Stateless relay catalog reducer.

Implementations§

Source§

impl RelayCatalogReducer

Source

pub fn reconcile( current: Vec<RelayCatalogEntry>, discovered: Vec<DnsRelayRecord>, refreshed_at: i64, fallback_url: String, dns_authenticated: bool, ) -> Result<RelayCatalogPlan, SoftchatError>

Reconcile persisted custom/exclusion state with authenticated discovery.

Discovery that is not explicitly authenticated never becomes trusted catalog state. The compiled fallback is used instead.

§Errors

Returns SoftchatError::InvalidRelayCatalog for invalid URLs, duplicate persisted rows, bounds, timestamps, priorities, weights, or TTLs.

Source

pub fn add_custom( current: Vec<RelayCatalogEntry>, relay_url: String, created_at: i64, ) -> Result<Vec<RelayCatalogEntry>, SoftchatError>

Add or reactivate a user-owned relay without discarding DNS metadata.

§Errors

Returns a stable relay-catalog error for malformed state or URL.

Source

pub fn exclude( current: Vec<RelayCatalogEntry>, relay_url: String, ) -> Result<Vec<RelayCatalogEntry>, SoftchatError>

Exclude an automatic relay or remove the custom ownership of a URL.

§Errors

Returns a stable relay-catalog error for an unknown or active-only URL.

Source

pub fn restore_automatic( current: Vec<RelayCatalogEntry>, ) -> Result<Vec<RelayCatalogEntry>, SoftchatError>

Restore every currently discovered automatic relay.

§Errors

Returns a stable relay-catalog error for malformed persisted rows.

Source

pub fn set_active( current: Vec<RelayCatalogEntry>, relay_url: String, ) -> Result<Vec<RelayCatalogEntry>, SoftchatError>

Select one effective active relay.

§Errors

Returns a stable relay-catalog error for an unknown/excluded target.

Source

pub fn failover_candidates( current: Vec<RelayCatalogEntry>, failed_url: String, ) -> Result<Vec<String>, SoftchatError>

Return effective failover URLs ordered by DNS priority then stable URL.

The failed URL is moved to the end rather than removed so a caller can continue cycling after every candidate fails.

§Errors

Returns a stable relay-catalog error for malformed persisted rows.
