These features can be disabled to make the engine Send + Sync, although it is recommended to only access the engine on a single thread to maintain optimal performance. The object-pooling and unsync-regex-caching features enable optimizations for rule matching speed and the amount of memory used by the engine. Thread safety ( object-pooling, unsync-regex-caching) The resource-assembler feature allows adblock-rust to parse these resources directly from the file formats used by the uBlock Origin repository. Parsing resources from uBlock Origin's formats ( resource-assembler)Īdblock-rust uses uBlock Origin-compatible resources for scriptlet injection and redirect rules. This is extremely useful to reduce binary bloat and improve consistency when embedding adblock-rust within a browser. For more advanced use-cases, disabling the embedded-domain-resolver feature will allow adblock-rust to use an external domain resolution implementation instead. External domain resolution ( embedded-domain-resolver)īy default, adblock-rust ships with a built-in domain resolution implementation (through the addr crate) that will generally suffice for standalone use-cases. Content blocking format translation ( content-blocking)Įnabling the content-blocking feature gives adblock-rust support for conversion of standard ABP-style rules into Apple's content-blocking format, which can be exported for use on iOS and macOS platforms. This will cause adblock-rust to reject cosmetic filter rules with invalid CSS syntax.

When parsing cosmetic filter rules, it's possible to include a built-in implementation of CSS validation (through the selectors and cssparser crates) by enabling the css-validation feature. CSS validation during rule parsing ( css-validation) The following cargo features can be used to tweak adblock-rust to best fit your use-case. See docs.rs for detailed API documentation.Īlso check the Rust example or the NodeJS example. Community-maintained Python bindings ( pypi)Īdblock-rust is used in several projects, including browsers, research tools, and proxies.Putting you back in control of your browsing experience.Īdblock-rust is the engine powering Brave's native adblocker, available as a library for anyone to use.
