Struct rustc_data_structures::obligation_forest::Node

struct Node<O> {
    obligation: O,
    state: Cell<NodeState>,
    dependents: Vec<usize>,
    has_parent: bool,
    obligation_tree_id: ObligationTreeId,
}

Fields

obligation: O

state: Cell<NodeState>

dependents: Vec<usize>

Obligations that depend on this obligation for their completion. They must all be in a non-pending state.

has_parent: bool

If true, dependents[0] points to a “parent” node, which requires special treatment upon error but is otherwise treated the same. (It would be more idiomatic to store the parent node in a separate Option<usize> field, but that slows down the common case of iterating over the parent and other descendants together.)

obligation_tree_id: ObligationTreeId

Identifier of the obligation tree to which this node belongs.

Implementations

impl<O> Node<O>

fn new( parent: Option<usize>, obligation: O, obligation_tree_id: ObligationTreeId ) -> Node<O>

Trait Implementations

impl<O: Debug> Debug for Node<O>

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

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
