Compile-Time Evaluation, Interpreted Rust, and UB Sanitizing: Talking to Oliver Scherer about Miri

In the first of our mini-interviews from RustFest 2019, we talk to Oliver Scherer about Miri, an interpreter for rustc’s internal bytecode, its use in const-evaluation, and its potential as an external tool for sanitizing unsafe code.
