# Global EVENT_SELECTORS

Module: `noir_aztec::macros::events`

```rust
pub mut comptime global EVENT_SELECTORS: CHashMap<Field, Quoted>;
```

A map from event selector to event name indicating whether the event selector has already been seen during the contract compilation - prevents event selector collisions.
