Struct MedrxivClient 

pub struct MedrxivClient { /* private fields */ }

Client for medRxiv.org preprint API

Provides methods to search for medical and health sciences preprints, filter by specialty, and convert results to SemanticVector format.

Categories

• Cardiovascular Medicine
• Infectious Diseases
• Oncology
• Public Health
• Epidemiology
• Psychiatry
• and many more…

Rate Limiting

The client automatically enforces a rate limit of ~1 request per second. Includes retry logic for transient failures.

Implementations

impl MedrxivClient

pub fn new() -> Self

Create a new medRxiv API client

Example

let client = MedrxivClient::new();

pub fn with_embedding_dim(embedding_dim: usize) -> Self

Create a new medRxiv API client with custom embedding dimension

Arguments

• embedding_dim - Dimension for text embeddings (default: 384)

pub async fn search_recent( &self, days: u64, limit: usize, ) -> Result<Vec<SemanticVector>>

Get recent preprints from the last N days

Arguments

• days - Number of days to look back (e.g., 7 for last week)
• limit - Maximum number of results to return

Example

// Get medical preprints from the last 7 days
let recent = client.search_recent(7, 100).await?;

pub async fn search_by_date_range( &self, start_date: NaiveDate, end_date: NaiveDate, limit: Option<usize>, ) -> Result<Vec<SemanticVector>>

Search preprints by date range

Arguments

• start_date - Start date (inclusive)
• end_date - End date (inclusive)
• limit - Optional maximum number of results

Example

use chrono::NaiveDate;

let start = NaiveDate::from_ymd_opt(2024, 1, 1).unwrap();
let end = NaiveDate::from_ymd_opt(2024, 12, 31).unwrap();
let papers = client.search_by_date_range(start, end, Some(200)).await?;

pub async fn search_covid(&self, limit: usize) -> Result<Vec<SemanticVector>>

Search COVID-19 related preprints

Arguments

• limit - Maximum number of results to return

Example

let covid_papers = client.search_covid(100).await?;

pub async fn search_clinical(&self, limit: usize) -> Result<Vec<SemanticVector>>

Search clinical research preprints

Arguments

• limit - Maximum number of results to return

Example

let clinical_papers = client.search_clinical(50).await?;
