Struct DanglingRef 

pub struct DanglingRef {
    pub holder: String,
    pub slot: String,
    pub value_type: &'static str,
    pub target_index: usize,
    pub table_len: usize,
}

A reference to an entity whose storage no longer exists.

Only possible once restore actually releases local VM: truncating an entity table makes every id at or above the new length invalid. Any surviving reference to one is a use-after-free, and indexing the table with it panics.

Fields

holder: String

Where the stale reference lives.

slot: String

Which slot inside the holder: a dict key, an array index, or a stack position.

value_type: &'static str

PostScript type name of the reference’s target.

target_index: usize

Entity index the reference points at.

table_len: usize

Current length of the entity table it points into.
