Editing Undefined behavior (section)

== Examples in Rust ==
While undefined behavior is never present in safe [[Rust (programming language)|Rust]], it is possible to invoke undefined behavior in unsafe Rust in many ways.<ref>{{cite web | title=Behavior considered undefined | website=The Rust Reference | url=https://doc.rust-lang.org/reference/behavior-considered-undefined.html | access-date=2022-11-28}}</ref> For example, creating an invalid reference (a reference which does not refer to a valid value) invokes immediate undefined behavior:

<syntaxhighlight lang="rust">
fn main() {
    // The following line invokes immediate undefined behaviour.
    let _null_reference: &i32 = unsafe { std::mem::zeroed() };
}
</syntaxhighlight>

It is not necessary to use the reference; undefined behavior is invoked merely from the creation of such a reference.
