Struct maplibre::render::graph::node::NodeState

pub struct NodeState {
    pub id: NodeId,
    pub name: Option<Cow<'static, str>>,
    pub type_name: &'static str,
    pub node: Box<dyn Node>,
    pub input_slots: SlotInfos,
    pub output_slots: SlotInfos,
    pub edges: Edges,
}

The internal representation of a Node, with all data required by the RenderGraph.

The input_slots and output_slots are provided by the node.

Fields

id: NodeId

name: Option<Cow<'static, str>>

type_name: &'static str

The name of the type that implements Node.

node: Box<dyn Node>

input_slots: SlotInfos

output_slots: SlotInfos

edges: Edges

Implementations

impl NodeState

pub fn new<T>(id: NodeId, node: T) -> Selfwhere
    T: Node,

Creates an NodeState without edges, but the input_slots and output_slots are provided by the node.

pub fn node<T>(&self) -> Result<&T, RenderGraphError>where
    T: Node,

Retrieves the Node.

pub fn node_mut<T>(&mut self) -> Result<&mut T, RenderGraphError>where
    T: Node,

Retrieves the Node mutably.

pub fn validate_input_slots(&self) -> Result<(), RenderGraphError>

Validates that each input slot corresponds to an input edge.

pub fn validate_output_slots(&self) -> Result<(), RenderGraphError>

Validates that each output slot corresponds to an output edge.

Trait Implementations

impl Debug for NodeState

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

Formats the value using the given formatter.
