Struct CallFrame

pub struct CallFrame<'gc, C: CustomTypes<S>, S: System<C>> {
    pub called_from: usize,
    pub entity: Gc<'gc, RefLock<Entity<'gc, C, S>>>,
    pub locals: SymbolTable<'gc, C, S>,
    /* private fields */
}

An entry in the call stack of a Process.

This contains information about the call origin and local variables defined in the called context.

Fields

called_from: usize

entity: Gc<'gc, RefLock<Entity<'gc, C, S>>>

locals: SymbolTable<'gc, C, S>

fn needs_trace() -> bool

As an optimization, if this type can never hold a Gc pointer and trace is unnecessary to call, you may implement this method and return false. The default implementation returns true, signaling that Collect::trace must be called.

fn trace(&self, cc: &Collection)

Must call Collect::trace on all held Gc pointers. If this type holds inner types that implement Collect, a valid implementation would simply call Collect::trace on all the held values to ensure this.
