Struct FredClient 

pub struct FredClient { /* private fields */ }

Client for FRED (Federal Reserve Economic Data)

Provides access to 800,000+ US economic time series including:

• GDP, unemployment, inflation, interest rates
• Money supply, consumer spending, housing data
• Regional economic indicators

Example

use ruvector_data_framework::FredClient;

let client = FredClient::new(None)?;
let gdp_data = client.get_gdp().await?;
let unemployment = client.get_unemployment().await?;
let search_results = client.search_series("inflation").await?;

Implementations

impl FredClient

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

Create a new FRED client

Arguments

• api_key - Optional FRED API key (get from https://fred.stlouisfed.org/docs/api/api_key.html) Basic access works without a key, but rate limits are more restrictive

pub async fn get_series( &self, series_id: &str, limit: Option<usize>, ) -> Result<Vec<SemanticVector>>

Get observations for a specific FRED series

Arguments

• series_id - FRED series ID (e.g., “GDP”, “UNRATE”, “CPIAUCSL”)
• limit - Maximum number of observations to return (default: 100)

Example

let gdp = client.get_series("GDP", Some(50)).await?;

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

Search for FRED series by keywords

Arguments

• keywords - Search terms (e.g., “unemployment rate”, “consumer price index”)

Example

let inflation_series = client.search_series("inflation").await?;

pub async fn get_gdp(&self) -> Result<Vec<SemanticVector>>

Get US GDP data (Gross Domestic Product)

Example

let gdp = client.get_gdp().await?;

pub async fn get_unemployment(&self) -> Result<Vec<SemanticVector>>

Get US unemployment rate

Example

let unemployment = client.get_unemployment().await?;

pub async fn get_cpi(&self) -> Result<Vec<SemanticVector>>

Get US Consumer Price Index (CPI) - inflation indicator

Example

let cpi = client.get_cpi().await?;

pub async fn get_interest_rate(&self) -> Result<Vec<SemanticVector>>

Get US Federal Funds Rate

Example

let interest_rates = client.get_interest_rate().await?;

pub async fn get_money_supply(&self) -> Result<Vec<SemanticVector>>

Get US M2 Money Supply

Example

let money_supply = client.get_money_supply().await?;
