Struct script::dom::globalscope::ManagedMessagePort
source · pub struct ManagedMessagePort {
dom_port: Dom<MessagePort>,
port_impl: Option<MessagePortImpl>,
pending: bool,
closed: bool,
}
Expand description
Data representing a message-port managed by this global.
Fields§
§dom_port: Dom<MessagePort>
The DOM port.
port_impl: Option<MessagePortImpl>
The logic and data backing the DOM port. The option is needed to take out the port-impl as part of its transferring steps, without having to worry about rooting the dom-port.
pending: bool
We keep ports pending when they are first transfer-received, and only add them, and ask the constellation to complete the transfer, in a subsequent task if the port hasn’t been re-transfered.
closed: bool
Has the port been closed? If closed, it can be dropped and later GC’ed.
