source ·
pub(super) struct Node {
    pub tag: BorTag,

Expand description

A node in the borrow tree. Each node is uniquely identified by a tag via the nodes map of Tree.

Fields§

§tag: BorTag

The tag of this node.

§parent: Option<UniIndex>

All tags except the root have a parent tag.

§children: SmallVec<[UniIndex; 4]>

If the pointer was reborrowed, it has children.

§default_initial_perm: Permission

Either Reserved, Frozen, or Disabled, it is the permission this tag will lazily be initialized to on the first access. It is only ever Disabled for a tree root, since the root is initialized to Active by its own separate mechanism.

§debug_info: NodeDebugInfo

Some extra information useful only for debugging purposes
