[−][src]Crate polyline_ffi
This module exposes functions for accessing the Polyline encoding and decoding functions via FFI
A Note on Coordinate Order
This crate uses Coordinate
and LineString
types from the geo-types
crate, which encodes coordinates in (x, y)
order. The Polyline algorithm and first-party documentation assumes the opposite coordinate order. It is thus advisable to pay careful attention to the order of the coordinates you use for encoding and decoding.
