feature.rs

1//! This module provides types and utilities for working with features in the `mvt-reader` crate.
2//!
3//! A feature represents a geographic entity with geometry and associated properties. Features are typically found within layers of a vector tile.
4//!
5//! # Types
6//!
7//! The `feature` module defines the following types:
8//!
9//! - `Feature`: Represents a feature with geometry, an optional id and optional properties.
