Crate wblidar 

wblidar

A high-performance, pure-Rust library for reading and writing LiDAR point-cloud data in the most common industry formats:

Format	Read	Write	Notes
LAS	✓	✓	versions 1.1 – 1.5; writes 1.4 R15 by default (v1.5 PDRF 11–15 also supported)
LAZ	✓	✓	standards-compliant LASzip v2/v3; in-house implementation, no LASzip C dependency
COPC	✓	✓	Cloud-Optimised Point Cloud (LAS 1.4 + EPT hierarchy)
PLY	✓	✓	ASCII & binary little/big-endian
E57	✓	✓	ASTM E2807; CRC-32 validation, optional zlib blobs

Design goals

• Minimal allocations – point records are streamed through a fixed-size PointRecord type; large arrays are written in a single pass.
• Minimal external dependencies – flate2 (zlib-ng backend) for DEFLATE streams in LAZ/E57 and wbprojection for CRS transforms.
• Reprojection helpers – use reproject::points_to_epsg (source CRS metadata) or reproject::points_from_to_epsg (explicit EPSG codes).
