Trait Implementations

impl<Meta: Clone + VmMeta> Clone for Pte<Meta>

fn clone(&self) -> Pte<Meta>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Meta: VmMeta> Debug for Pte<Meta>

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

Formats the value using the given formatter.

impl<Meta: PartialEq + VmMeta> PartialEq for Pte<Meta>

fn eq(&self, other: &Pte<Meta>) -> 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.
