fastobo

Faultless AST for Open Biomedical Ontologies.

Overview

This library provides an abstract syntax tree for the OBO flat file format 1.4.

Usage

Add fastobo to the [dependencies] sections of your Cargo.toml manifest: toml [dependencies] fastobo = "0.1.0"

The OboDoc struct acts as the root of the AST. Use OboDoc::from_stream to load an OBO document from a BufRead implementor (use std::io::BufReader if needed):

```rust extern crate fastobo; extern crate reqwest;

fn main() { let response = reqwest::get("http://purl.obolibrary.org/obo/go.obo").unwrap(); let mut reader = std::io::BufReader::new(response);

match fastobo::ast::OboDoc::from_stream(&mut reader) {
    Ok(doc) => println!("Number of GO entities: {}", doc.entities.len()),
    Err(e) => panic!("Could not parse the Gene Ontology: {}", e),
}

} ```

Missing features

• [ ] Support for comment blocks between frames
• [ ] Support for comments in property_value clauses in headers.
• [ ] More std traits implementation.
