Struct adblock::regex_manager::RegexManager

pub struct RegexManager { /* private fields */ }

A manager that creates and stores all regular expressions used by filters. Rarely used entries are discarded to save memory.

The RegexManager is not thread safe, so any access to it must be synchronized externally.

Implementations

impl RegexManager

pub fn matches(&mut self, filter: &NetworkFilter, pattern: &str) -> bool

Check whether or not a regex network filter matches a certain URL pattern, using the RegexManager’s managed regex storage.

pub fn update_time(&mut self)

The RegexManager is just a struct and doesn’t manage any worker threads, so this method must be called periodically to ensure that it can track usage patterns of regexes over time. This method will handle periodically discarding filters if necessary.

pub fn set_discard_policy( &mut self, new_discard_policy: RegexManagerDiscardPolicy, )

Customize the discard behavior of this RegexManager.

Trait Implementations

impl Default for RegexManager

fn default() -> Self

Returns the “default value” for a type.

impl Send for RegexManager

*const NetworkFilter could technically leak across threads through RegexDebugEntry::id, but it’s disguised as a unique identifier and not intended to be dereferenced.
