Lib.rs

Simple Openstreetmap PBF file format reader. http://wiki.openstreetmap.org/wiki/PBF_Format

This lib uses multithreaded approach for reading data and optimized for speed :D.

Serial read can be achieved by restricting number of additional concurent threads to 0.

For example usate see src/lib.rs tests. There is GUI example which can be run using cargo run --release --example paint

DONE:

• reading Nodes, Ways, Relatons, Tags

TODO:

• build index for faster read access.
• filtered read.
• documentation and examples.
• template float and ID types for tunable storage precision.

Principle #1 User can't catch more than ~5mb of text+vector data from a 4"-6" screen.
