Trait Implementations

impl Debug for OTP

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for OTP

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for OTP

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
