Struct VarPtr

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

Represents an AnyVar pointer that can be used for comparison.

If two of these values are equal, both variables point to the same arc or context at the moment of comparison.

Implementations

impl<'a> VarPtr<'a>

pub fn raw_pointer(&self) -> *const ()

Gets the pointer.

Safety

Trying to read or write values using this pointer is never safe.

Trying to identify a variable using the raw pointer is only valid if you know the variable is still alive. The variable could be dropped and new one allocated at the same address.

Trait Implementations

impl Debug for VarPtr<'_>

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

Formats the value using the given formatter.

impl PartialEq for VarPtr<'_>

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

Tests for self and other values to be equal, and is used by ==.

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

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