Struct MaterialsProjectClient 

pub struct MaterialsProjectClient { /* private fields */ }

Client for Materials Project

Provides access to:

• Computational materials science database
• Crystal structures and properties
• Band gaps, formation energies
• Electronic and mechanical properties

Note: Requires API key from https://materialsproject.org

Example

use ruvector_data_framework::MaterialsProjectClient;

let client = MaterialsProjectClient::new("YOUR_API_KEY".to_string())?;
let silicon = client.search_materials("Si").await?;
let material = client.get_material("mp-149").await?;
let semiconductors = client.search_by_property("band_gap", 1.0, 3.0).await?;

Implementations

impl MaterialsProjectClient

pub fn new(api_key: String) -> Result<Self>

Create a new Materials Project client

Arguments

• api_key - Materials Project API key (get from https://materialsproject.org)

pub async fn search_materials( &self, formula: &str, ) -> Result<Vec<SemanticVector>>

Search materials by chemical formula

Arguments

• formula - Chemical formula (e.g., “Si”, “Fe2O3”, “LiFePO4”)

Example

let silicon = client.search_materials("Si").await?;
let iron_oxide = client.search_materials("Fe2O3").await?;

pub async fn get_material( &self, material_id: &str, ) -> Result<Vec<SemanticVector>>

Get a specific material by Materials Project ID

Arguments

• material_id - Materials Project ID (e.g., “mp-149” for silicon)

Example

let silicon = client.get_material("mp-149").await?;

pub async fn search_by_property( &self, property: &str, min: f64, max: f64, ) -> Result<Vec<SemanticVector>>

Search materials by property range

Arguments

• property - Property name (e.g., “band_gap”, “formation_energy_per_atom”)
• min - Minimum value
• max - Maximum value

Example

// Find semiconductors with band gap 1-3 eV
let semiconductors = client.search_by_property("band_gap", 1.0, 3.0).await?;
