e018: `Borrow`, `AsRef`, `Deref`: my head hurts now - a podcast by Chris Krycho

Three traits which are essential for designing good, Rustic APIs.

Notes

Borrow, AsRef, and Deref are a little complicated, but they're well-worth understanding. Together, they give you tools for dealing with everything from HashMap and friends to conversions involving smart pointer types to easily using String and str or Vec and slice together.
