new StackEntry(): StackEntry
Returns:StackEntry
Attributes
directory:boolean
fragment:string
module:boolean
name:string
parent:StackEntry
path:string | false
preSeeded:Set<string>
Strings seeded by callers that still pass stack: new Set([...]) . Propagated through the chain so deeper doResolve calls still see them during recursion checks. undefined in the common case so there is no extra work on the hot path.
query:string
request:string
size:number
Number of entries on the stack (oldest-to-newest length).
has(query): boolean
Attributes
query:StackEntry
Returns:boolean

Walk the linked list looking for an entry with the same request shape. Set-compatible: callers that used stack.has(entry) keep working. NOTE: kept monomorphic on purpose. An earlier draft accepted a string query too (so pre-5.21 plugins keeping their own Set<string> of seen entries could probe the live stack with the formatted form), but adding the second shape regressed doResolve's heap profile by ~1 MiB / 200 resolves on stack-churn — V8 keeps a polymorphic call-site state for parent.has(stackEntry) once has has two argument shapes. Plugins that need string membership can reach for [...stack].find(e => e.includes(formattedString)) via the String-method proxies on StackEntry instead.

toString(): string
Returns:string

Human-readable form used in recursion error messages, logs, and the iterator above. Not memoized: caching would require an extra slot on every StackEntry, which costs heap even on resolves that never look at the formatted form.
