Struct FilteredPreHook 

pub struct FilteredPreHook<H: PreHook> { /* private fields */ }

A PreHook wrapper that runs the inner hook only when matcher passes. On mismatch, returns HookAction::Noop without invoking the inner hook. Allocation: none per call when matcher fails. Complexity: O(matcher check).

Implementations

impl<H: PreHook> FilteredPreHook<H>

pub fn new(hook: H, matcher: HookMatcher) -> Self

Wrap hook so it only fires when matcher passes. Allocation: one HookMatcher clone. Complexity: O(1).
