# `TryFrom` and `TryInto`
In the previous chapter we looked at the [`From` and `Into` traits](../04_traits/09_from.md),
Rust's idiomatic interfaces for **infallible** type conversions.

But what if the conversion is not guaranteed to succeed?

The main difference between `From`/`Into` and `TryFrom`/`TryInto` is that the latter return a `Result` type.

This allows the conversion to fail, returning an error instead of panicking.

If you implement `TryFrom` for a type, you get `TryInto` for free.
