Struct boa_engine::object::RecursionLimiter
source · pub struct RecursionLimiter {
pub visited: bool,
pub live: bool,
/* private fields */
}
Expand description
Prevents infinite recursion during Debug::fmt
, JSON.stringify
, and other conversions.
This uses a thread local, so is not safe to use where the object graph will be traversed by
multiple threads!
Fields§
§visited: bool
If this JsObject has been visited before in the graph, but not in the current branch.
live: bool
If this JsObject has been visited in the current branch of the graph.
Implementations§
source§impl RecursionLimiter
impl RecursionLimiter
sourcepub fn new<T: ?Sized>(o: &T) -> Self
pub fn new<T: ?Sized>(o: &T) -> Self
Determines if the specified T
has been visited, and returns a struct that will free it when dropped.
This is done by maintaining a thread-local hashset containing the pointers of T
values that have been
visited. The first T
visited will clear the hashset, while any others will check if they are contained
by the hashset.
