Struct gazebo::cmp::PartialEqAny

source · [−]

pub struct PartialEqAny<'a> { /* private fields */ }

Expand description

A comparable “token” that can be returned to wrap a reference to an Any type for PartialEq.

This lets dyn traits be comparable by having all implementations return some “token” that can be considered PartialEq.

Implementations

source

impl<'a> PartialEqAny<'a>

source

pub fn new<A: PartialEq + 'static>(a: &'a A) -> Self

source

pub fn always_false() -> Self

gets an instance that always compares to false

Trait Implementations

source

impl<'a> PartialEq<PartialEqAny<'a>> for PartialEqAny<'a>

source

fn eq(&self, other: &PartialEqAny<'a>) -> bool

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

1.0.0 · source

const 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. Read more

source

impl<T> AsARef<T> for Twhere

source

fn as_aref(this: &T) -> ARef<'_, T>

Get an ARef pointing at this type.

source

fn try_as_aref(this: &T) -> Result<ARef<'_, T>, BorrowError>
