Rust in cURL

Rustacean Station

First time guest host, Allen Wyma talks with Daniel, the original author of cURL, about using Rust in cURL.

• cURL is a command line tool and library for transferring data with URLs.
• cURL, and its data transfer core, libcurl are both written in C, which is known to be not memory safe.
• While it is almost impossibe to rewrite it into another language, offering a third-party library written in Rust could take a further step forward.
