Struct TrapMatcher 

pub struct TrapMatcher { /* private fields */ }

Compiled trap pattern matcher.

Uses RegexSet for O(1) matching in the hot path. The original pattern names are preserved in config.paths for logging when a trap is hit.

Implementations

impl TrapMatcher

pub fn new(config: TrapConfig) -> Result<Self, Error>

Create a new TrapMatcher from configuration.

pub fn is_trap(&self, path: &str) -> bool

Check if a path matches any trap pattern.

Uses RegexSet::is_match() for O(1) matching performance on the hot path. This is called on every request, so performance is critical.

pub fn config(&self) -> &TrapConfig

Get the trap configuration.

pub fn matched_pattern(&self, path: &str) -> Option<&str>

Get the matched trap pattern for a path (for logging).

This is only called after is_trap() returns true, so it’s not on the hot path. Uses RegexSet::matches() to get all matching pattern indices efficiently.
