Struct LEFDesignRuleAdapter 

pub struct LEFDesignRuleAdapter<'a, L: LayoutBase> { /* private fields */ }

Provides standardized read access to the design-rules defined in a LEF structure.

Implementations

impl<'a, L> LEFDesignRuleAdapter<'a, L>

where L: LayoutBase, L::Coord: FromPrimitive + ToPrimitive,

pub fn new(lef: &'a LEF, layout: &L) -> Self

Create a new design rule adapter for a LEF data structure. Derives the mapping from layer IDs and LEF layers based on the layer names.

pub fn new_from_layer_mapping( lef: &'a LEF, layer_ids_by_name: &HashMap<String, L::LayerId>, dbu: f64, ) -> Self

Create a new design rule adapter for a LEF data structure with a custom mapping between layer names and layer IDs.
