Summary
totally-safe-transmute allows transmuting any type to any other type in safe Rust
Details
This crate is a toy and should never be used.
It showcases a known soundness issue (https://github.com/rust-lang/rust/issues/32670) that will never get fixed. In short, Linux provides a file called /proc/self/mem which can be used by a program to modify its own memory. This library modifies an enum variant number by accessing its own memory as a file to effectively transmute a variable.
