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.
