# Unsound `impl Follow for bool`
|
|
|
|
The implementation of `impl Follow for bool` allows to reinterpret arbitrary bytes as a `bool`.
|
|
|
|
In Rust `bool` has stringent requirements for its in-memory representation. Use of this function
|
|
allows to violate these requirements and invoke undefined behaviour in safe code.
