pubchem.rs

Rust data structures and client for the PubChem REST API.

🔌 Usage

💊 Compound

Create a Compound to query the PubChem API for a single compound. It can be constructed from a compound ID, from a compound name, from an InChI or InChIKey, or from a SMILES string:

```rust extern crate pubchem;

let alanine = pubchem::Compound::new(5950); let aspirin = pubchem::Compound::withname("aspirin"); let acetone = pubchem::Compound::withinchi("InChI=1S/C3H6O/c1-3(2)4/h1-2H3"); let lysine = pubchem::Compound::withinchikey("KDXKERNSBIXSRK-YFKPBYRVSA-N"); let benzene = pubchem::Compound::withsmiles("C1=CC=CC=C1"); ```

Use the methods to query the REST API with ureq. Dedicated methods exist for common single properties:

```rust let alanine = pubchem::Compound::new(5950);

alanine.title().unwrap(); // "Alanine" alanine.molecularformula().unwrap(); // "C3H7NO2" alanine.canonicalsmiles().unwrap(); // "CC(C(=O)O)N" alanine.isomeric_smiles().unwrap(); // "CC@@HN" ```

Each method will perform a single query to the PubChem API, which is inefficient if you wish to retrieve several properties at once. In that case, use the properties method and select which properties you want to retrieve in a single query:

```rust use pubchem::CompoundProperty::*;

let properties = pubchem::Compound::new(5950) .properties(&[Title, MolecularFormula, CanonicalSMILES]) .unwrap();

properties.molecularformula; // Some("C3H7NO2") properties.canonicalsmiles; // Some("CC(C(=O)O)N") properties.isomeric_smiles; // Some("CC@@HN") ```
