Struct LayoutGraph 

pub struct LayoutGraph {
    pub nodes: Vec<LayoutNode>,
    pub edges: Vec<LayoutEdge>,
    pub id_to_node: BTreeMap<String, usize>,
    pub in_node: usize,
    pub out_node: usize,
    pub vcc_node: usize,
    pub gnd_node: usize,
    pub net_groups: Vec<NetGroup>,
    pub monitor_ids: Vec<String>,
}

Directed graph built from the .pedal netlist for layout purposes.

Fields

nodes: Vec<LayoutNode>

edges: Vec<LayoutEdge>

id_to_node: BTreeMap<String, usize>

Map from component ID to node index.

in_node: usize

Index of the in anchor node.

out_node: usize

Index of the out anchor node.

vcc_node: usize

Index of the vcc anchor node.

gnd_node: usize

Index of the gnd anchor node.

net_groups: Vec<NetGroup>

Merged net groups: each group is a set of pins that are connected.

monitor_ids: Vec<String>

Monitor component IDs from the pedal definition.

Implementations

impl LayoutGraph

pub fn from_pedal(pedal: &PedalDef) -> Self

Build a layout graph from a parsed pedal definition.

pub fn outgoing(&self, node_id: usize) -> Vec<&LayoutEdge>

Get all outgoing edges from a node.

pub fn incoming(&self, node_id: usize) -> Vec<&LayoutEdge>

Get all incoming edges to a node.

pub fn neighbors(&self, node_id: usize) -> BTreeSet<usize>

Get all neighbors (both directions) of a node.

pub fn connects_to_vcc(&self, node_id: usize) -> bool

Check if a node connects to vcc (directly or through supply components).

pub fn connects_to_gnd(&self, node_id: usize) -> bool

Check if a node connects to gnd (directly or through ground components).

pub fn node_kind(&self, node_id: usize) -> Option<&dyn Component>

Get the component kind for a node, if it has one.

pub fn is_active_device(&self, node_id: usize) -> bool

Check if a node is an active device (tube, transistor, op-amp).

pub fn is_passive(&self, node_id: usize) -> bool

Check if a component is a simple passive (R, C, L — not pot/transformer).

Trait Implementations

impl Debug for LayoutGraph

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

Formats the value using the given formatter.
