Implementations

impl NodeType

pub fn display_name(&self) -> &'static str

Human-readable display name.

pub fn category(&self) -> &'static str

Category string for grouping in a UI palette.

pub fn is_output(&self) -> bool

Whether this node type is an output sink (terminal node).

pub fn is_pure_math(&self) -> bool

Whether this node is a pure math operation (eligible for constant folding).

pub fn is_source(&self) -> bool

Whether this node is a source that requires no inputs from other nodes.

pub fn instruction_cost(&self) -> u32

Estimated GPU instruction cost of this node (for budgeting).

pub fn default_inputs(&self) -> Vec<Socket>

Build the default input sockets for this node type.

pub fn default_outputs(&self) -> Vec<Socket>

Build the default output sockets for this node type.

pub fn generate_glsl( &self, var_prefix: &str, input_vars: &[String], ) -> GlslSnippet

Generate the GLSL code snippet for this node.

var_prefix is the unique variable name prefix for this node instance (e.g., “n42”). input_vars maps input socket index to the GLSL expression feeding it.

Returns a vector of (line_of_code, output_socket_index).

Trait Implementations

impl Clone for NodeType

fn clone(&self) -> NodeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeType

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

Formats the value using the given formatter.

impl PartialEq for NodeType

fn eq(&self, other: &NodeType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
