Implementations

impl ShaderGraph

pub fn new(name: &str) -> Self

Create a new empty shader graph.

pub fn alloc_id(&mut self) -> NodeId

Allocate a fresh node ID.

pub fn add_node(&mut self, node_type: NodeType) -> NodeId

Add a node to the graph, returning its ID.

pub fn add_node_with(&mut self, node: ShaderNode) -> NodeId

Add a pre-built node to the graph.

pub fn insert_node(&mut self, node: ShaderNode) -> NodeId

Add a pre-built node, reusing its existing ID if set, or allocating one.

pub fn connect( &mut self, from_node: NodeId, from_socket: usize, to_node: NodeId, to_socket: usize, )

Connect an output socket of one node to an input socket of another.

pub fn disconnect_node(&mut self, node_id: NodeId)

Remove all connections involving a node.

pub fn disconnect( &mut self, from_node: NodeId, from_socket: usize, to_node: NodeId, to_socket: usize, )

Remove a specific connection.

pub fn remove_node(&mut self, node_id: NodeId)

Remove a node and all its connections.

pub fn node(&self, id: impl Borrow<NodeId>) -> Option<&ShaderNode>

Get a reference to a node.

pub fn node_mut(&mut self, id: NodeId) -> Option<&mut ShaderNode>

Get a mutable reference to a node.

pub fn nodes(&self) -> impl Iterator<Item = &ShaderNode>

Iterate over all nodes.

pub fn node_ids(&self) -> impl Iterator<Item = NodeId> + '_

Iterate over all node IDs.

pub fn node_count(&self) -> usize

Number of nodes.

pub fn connections(&self) -> &[Connection]

Get all connections.

pub fn incoming_connections(&self, node_id: NodeId) -> Vec<&Connection>

Get connections feeding into a specific node’s input socket.

pub fn outgoing_connections(&self, node_id: NodeId) -> Vec<&Connection>

Get connections going out of a specific node.

pub fn output_nodes(&self) -> Vec<NodeId>

Find all output nodes (MainColor, EmissionBuffer, BloomBuffer, NormalOutput).

pub fn source_nodes(&self) -> Vec<NodeId>

Find all source nodes (no required input connections).

pub fn estimated_cost(&self) -> u32

Compute the total estimated instruction cost of the graph.

pub fn validate(&self) -> Vec<String>

Validate basic graph integrity: all connections reference existing nodes, socket indices are in range, no self-loops.

pub fn topology_hash(&self) -> u64

Compute a topology hash for caching/deduplication.

pub fn nodes_map(&self) -> &HashMap<NodeId, ShaderNode>

Return the internal nodes map (used for serialization).

pub fn next_id_counter(&self) -> u64

Return the next_id counter (used for serialization).

pub fn set_next_id(&mut self, val: u64)

Set the next_id counter (used during deserialization).

pub fn add_connection_raw(&mut self, conn: Connection)

Add a raw connection without duplicate-input removal (used during deserialization).

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ShaderGraph

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

impl Default for ShaderGraph

fn default() -> Self

Returns the “default value” for a type.
