Crate pbf_craft 

A pure-Rust library for reading and writing OpenStreetMap PBF (Protocolbuffer Binary Format) files.

Modules

• models — the OSM element model: models::Node, models::Way, models::Relation and the models::Element enum, with coordinates in integer nanodegrees.
• readers — a family of readers for different scenarios:
  • readers::PbfReader — sequential streaming reader (single- or multi-threaded filtering via readers::PbfReader::par_find).
  • readers::IterableReader — iterator-based reader with byte progress reporting (readers::ReaderProgress).
  • readers::IndexedReader — random access by element id, backed by a .pif index file, with an in-memory blob cache and dependency resolution (readers::IndexedReader::get_with_deps).
• writers — writers::PbfWriter, a streaming writer producing zlib-compressed blobs with dense-node support.

Examples

Read PBF data from a file:

use pbf_craft::readers::PbfReader;

let mut reader = PbfReader::from_path("resources/andorra-latest.osm.pbf").unwrap();
reader.read(|header, element| {
    if let Some(header_reader) = header {
        // Process header
    }
    if let Some(element) = element {
        // Process element
    }
}).unwrap();

Read PBF data with dependencies:

use pbf_craft::models::ElementType;
use pbf_craft::readers::IndexedReader;

let mut indexed_reader =
    IndexedReader::from_path_with_cache("resources/andorra-latest.osm.pbf", 1000).unwrap();
let element_list = indexed_reader.get_with_deps(&ElementType::Way, 12345678).unwrap();

Write PBF data to a file:

use pbf_craft::models::{Element, Node};
use pbf_craft::writers::PbfWriter;

let mut writer = PbfWriter::from_path(std::env::temp_dir().join("output.osm.pbf"), true).unwrap();
writer.write(Element::Node(Node::default())).unwrap();
writer.finish().unwrap();

Data format notes

• Coordinates: Node/WayNode/Bound coordinates are i64 nanodegrees (the raw PBF unit; divide by 1e9 for degrees).
• Ordering: the PBF format does not require sorted elements, but the conventional layout (all nodes by id, then all ways by id, then all relations by id) is assumed by IndexedReader and most other tools. PbfWriter stores elements in the order written — the caller is responsible for the order.
• Compression: reading supports raw, zlib, lz4 and zstd blobs; writing produces zlib-compressed blobs.
• visible flag: elements default to visible = true (per spec, the flag is assumed true when absent). Elements explicitly marked visible = false are written with the required HistoricalInformation feature declared in the header.
• Error handling: all fallible operations return anyhow::Result; malformed or truncated input surfaces as errors rather than panics.
