ChemCore

A cheminformatics toolkit for Rust.

ChemCore provides primitives for working with Molecules. For details, see: ChemCore: A Cheminformatics Toolkit for Rust.

Usage

Add this to your Cargo.toml:

toml [dependencies] chemcore = "0.4.0"

Examples

Parse cyclopropane SMILES, traverse in depth-first order, and query its Molecule and Graph traits:

```rust use gamma::graph::{ Graph }; use gamma::traversal::{ DepthFirst, Step }; use chemcore::daylight::{ read_smiles, SmilesInputError }; use chemcore::molecule::{ Atom, Element, Molecule, Error };

fn main() -> Result<(), SmilesInputError> { let molecule = read_smiles(&"C1CC1", None)?; let traversal = DepthFirst::new(&molecule, 0).expect("traversal error");

assert_eq!(traversal.collect::<Vec<_>>(), vec![
    Step::new(0, 2, false),
    Step::new(2, 1, false),
    Step::new(1, 0, true)
]);

// Graph trait
assert_eq!(molecule.degree(0), Ok(2));
assert_eq!(molecule.size(), 3);
assert_eq!(molecule.order(), 3);

// Molecule trait
assert_eq!(molecule.atom(0), Ok(&Atom {
    isotope: None,
    element: Some(Element::C),
    hydrogens: 2,
    electrons: 0,
    parity: None,
}));
assert_eq!(molecule.charge(0), Ok(0.));
assert_eq!(molecule.bond_order(0, 1), Ok(1.));

Ok(())

} ```
