}

Describe the different families of dependency nodes.

Required Associated Constants

const NULL: Self

DepKind to use when incr. comp. is turned off.

const RED: Self

DepKind to use to create the initial forever-red node.

Required Methods

fn debug_node(node: &DepNode<Self>, f: &mut Formatter<'_>) -> Result

Implementation of std::fmt::Debug for DepNode.

fn with_deps<OP, R>(deps: TaskDepsRef<'_, Self>, op: OP) -> Rwhere
    OP: FnOnce() -> R,

Execute the operation with provided dependencies.

fn read_deps<OP>(op: OP)where
    OP: for<'a> FnOnce(TaskDepsRef<'a, Self>),

Access dependencies from current implicit context.
