Crate polylineffi

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.

Structs

• ExternalArray
  A C-compatible struct originating outside Rust used for passing arrays across the FFI boundary
• InternalArray
  A C-compatible struct originating inside Rust used for passing arrays across the FFI boundary

Functions

• decode_polyline_ffi^⚠
  Convert a Polyline into an array of coordinates
• drop_cstring^⚠
  Free CString memory which Rust has allocated across the FFI boundary
• drop_float_array
  Free Array memory which Rust has allocated across the FFI boundary
• encode_coordinates_ffi
  Convert an array of coordinates into a Polyline
