Struct CellRef

pub struct CellRef<'a, H: HierarchyBase + ?Sized> { /* private fields */ }

A reference to a cell. This is just a wrapper around a netlist and a cell ID.

Trait Implementations

impl<'a, H: HierarchyBase> Clone for CellRef<'a, H>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, H: HierarchyBase> Debug for CellRef<'a, H>

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

Formats the value using the given formatter.

impl<'a, H: HierarchyBase> PartialEq for CellRef<'a, H>

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.
