Struct Thunk 

pub struct Thunk {
    pub node: Node,
    pub scope: Arc<Scope>,
    pub path: Vec<String>,
    pub cache_key: String,
    pub value: Mutex<Option<Value>>,
}

A lazily-evaluated dict entry. The first access through Evaluator::force_thunk parses + evaluates node against scope and caches the result in value; later accesses return the cached value.

All fields are pub so that backend crates (currently relon-evaluator) can read the captured node / scope when forcing the thunk — they live in a distinct crate from Thunk, so a pub(crate) visibility would block them.

Fields

node: Node

scope: Arc<Scope>

path: Vec<String>

cache_key: String

value: Mutex<Option<Value>>

Implementations

impl Thunk

pub fn new( node: Node, scope: Arc<Scope>, path: Vec<String>, cache_key: String, ) -> Self
