Struct always_equal::prod::AlwaysEqual

pub struct AlwaysEqual<T> { /* private fields */ }

In prod mode, AlwaysEqual <T> has the same size as T. Debug and Display are passed through if T implements them. PartialEq always returns false in prod mode.

Wrapping a string, checking its equality, and unwrapping it:

use always_equal::prod::AlwaysEqual;
 
let s = "some string";
let a = AlwaysEqual::from (s);
let b = AlwaysEqual::from (s);
assert_ne! (a, b);
let s2 = a.into_inner ();

pub fn into_inner(self) -> T

Trait Implementations

impl<T: Debug> Debug for AlwaysEqual<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for AlwaysEqual<T>

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

Formats the value using the given formatter.

impl<T> From<T> for AlwaysEqual<T>

fn from(inner: T) -> Self

Converts to this type from the input type.

impl<T> PartialEq<AlwaysEqual<T>> for AlwaysEqual<T>

fn eq(&self, _other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
