Struct SkNode 

pub struct SkNode {
    pub name: String,
    pub output: SkOutput,
    pub ast: AstNode,
    pub vars: Vec<(String, String)>,
    pub cache: RefCell<Option<(f64, u64)>>,
}

SwissKnife node evaluating an arithmetic expression referencing other nodes.

Integer outputs follow round-to-nearest semantics with ties towards zero after the expression has been evaluated as f64.

Fields

name: String

Unique feature name.

output: SkOutput

Desired output type as declared in the XML.

ast: AstNode

Parsed expression AST.

vars: Vec<(String, String)>

Mapping of variable identifiers to provider node names.

cache: RefCell<Option<(f64, u64)>>

Cached value alongside the generation it was computed in.
