//! Event filtering logic
//!
//! Provides a standalone `matches` function that delegates to
//! `EventFilter::matches()` for use by the subscription and streaming layers.

use crate::types::{EventEnvelope, EventFilter};

/// Returns `true` if the envelope passes all filter predicates.
///
/// This is a convenience wrapper around [`EventFilter::matches`] for use
/// in contexts where a free function is preferred (e.g., iterator adapters).
pub fn matches(filter: &EventFilter, envelope: &EventEnvelope) -> bool {
    filter.matches(envelope)
}
