Struct halo2_proofs::dev::CircuitLayout
source · pub struct CircuitLayout { /* private fields */ }
Expand description
Graphical renderer for circuit layouts.
Cells that have been assigned to by the circuit will be shaded. If any cells are assigned to more than once (which is usually a mistake), they will be shaded darker than the surrounding cells.
§Examples
ⓘ
use halo2_proofs::dev::CircuitLayout;
use plotters::prelude::*;
let drawing_area = BitMapBackend::new("example-circuit-layout.png", (1024, 768))
.into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
let drawing_area = drawing_area
.titled("Example Circuit Layout", ("sans-serif", 60))
.unwrap();
let circuit = MyCircuit::default();
let k = 5; // Suitable size for MyCircuit
CircuitLayout::default().render(k, &circuit, &drawing_area).unwrap();
Implementations§
source§impl CircuitLayout
impl CircuitLayout
sourcepub fn show_labels(self, show: bool) -> CircuitLayout
pub fn show_labels(self, show: bool) -> CircuitLayout
Sets the visibility of region labels.
The default is to show labels.
sourcepub fn mark_equality_cells(self, show: bool) -> CircuitLayout
pub fn mark_equality_cells(self, show: bool) -> CircuitLayout
Marks cells involved in equality constraints, in red.
The default is to not mark these cells.
sourcepub fn show_equality_constraints(self, show: bool) -> CircuitLayout
pub fn show_equality_constraints(self, show: bool) -> CircuitLayout
Draws red lines between equality-constrained cells.
The default is to not show these, as they can get very messy.
sourcepub fn view_width(self, width: Range<usize>) -> CircuitLayout
pub fn view_width(self, width: Range<usize>) -> CircuitLayout
Sets the view width for this layout, as a number of columns.
sourcepub fn view_height(self, height: Range<usize>) -> CircuitLayout
pub fn view_height(self, height: Range<usize>) -> CircuitLayout
Sets the view height for this layout, as a number of rows.
