Struct adblock::cosmetic_filter_cache::HostnameRuleDb

pub struct HostnameRuleDb { /* fields omitted */ }

Implementations

impl HostnameRuleDb

Each hostname-specific filter can be pointed to by several different hostnames, and each hostname can correspond to several different filters. To effectively store and access those filters by hostname, all the non-hostname information for filters is stored in per-hostname "buckets" within a Vec, and each bucket is identified by its index. Hostname hashes are used as keys to get the indices of relevant buckets, which are in turn used to retrieve all the filters that apply.
