Crag
A crate for searching the web.
Overview
Crag provides a generic [SOAP] (search over any protocol: a wildly grandiose acronym for a trait that provides a search function) trait that can be implemented for various search engines,
and supports these engines out of the box:
- Qwant
Search engines consume a Query, that specifies the search parameters,
and return a vector of structured SearchResults.
Example
use crag::{Query, Soap};
use crag::engines::Qwant;
// Create a new query and search engine
let query = Query::from("rust programming language");
let engine = Qwant::default();
// Perform the search using our query and engine
let results = engine.search(query).unwrap();
// Print the results
for (idx, item) in results.iter().enumerate() {
println!("\n{}. {item}\n", idx + 1);
}Command Line Interface
Crag also provides a command line interface for searching the web.
You can install it for your platform with cargo install crag, and easily search the web from the command line:

Rust is a multi-paradigm, high-level, general-purpose programming language.Rust emphasizes performance, type safety, and concurrency.Rust enforces memory safety—that is, that all references point to valid memory—without requiring the use of a garbage collector or reference counting present in other memory-safe languages. To simultaneously enforce memory safety and prevent concurrent data ...
