# A5 Wireframe Example
This example generates A5 cell boundaries at a given resolution and outputs them as a GeoJSON FeatureCollection. This replicates the functionality of the Python wireframe example found in `git/a5-py/examples/wireframe/index.py`.
## Usage
```bash
cargo run --example wireframe <resolution> <output.json>
```
Where:
- `resolution`: A5 cell resolution (integer)
- `output.json`: Path to the output GeoJSON file
## Examples
Generate all cells at resolution 0 (12 cells covering the entire world):
```bash
cargo run --example wireframe 0 world-res0.json
```
Generate all cells at resolution 1 (60 cells):
```bash
cargo run --example wireframe 1 world-res1.json
```
Generate all cells at resolution 2 (240 cells):
```bash
cargo run --example wireframe 2 world-res2.json
```
## Output Format
The output is a GeoJSON FeatureCollection where each feature represents an A5 cell with:
- Polygon geometry containing the cell boundary coordinates
- Properties including the hexadecimal cell ID
## Testing
Run the example tests:
```bash
cargo test --example wireframe
```
## Verification
To verify the port is working correctly, you can compare the output with the Python version:
```bash
# Generate with Python (from a5-py directory)
cd /Users/work/git/a5-py/examples/wireframe
python3 index.py 0 python-output.json
# Generate with Rust
cd /Users/work/git/a5-rs
cargo run --example wireframe 0 rust-output.json
# Compare cell counts and cell IDs
```
Both implementations should generate the same number of cells with the same cell IDs at each resolution.
