Struct libreda_db::reference_access::CellRef

pub struct CellRef<'a, H: HierarchyBase + ?Sized> {
    pub(super) base: &'a H,
    pub(super) id: H::CellId,
}

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

Fields

base: &'a H

Reference to the parent data structure.

id: H::CellId

ID of the corresponding cell.

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<CellRef<'a, H>> for CellRef<'a, H>

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.
