Struct sandbox_ipc::MessageChannel [−][src]
pub struct MessageChannel<T, R> where
T: Serialize,
R: for<'de> Deserialize<'de>, { /* fields omitted */ }
A basic channel for sending serializable types between processes.
MessageChannel
s are the fundamental IPC primitive in the crate. Most other primitives must be sent across a MessageChannel
before they can be used to communicate. They are initially best established by between parent and child processes
via MessageChannel::establish_with_child
, but they can also be connected by name via NamedMessageChannel
. Once initial
channels are established, further channels can be set up by creating PreMessageChannel
pairs and sending them to their final destinations.
MessageChannel
s are capable of sending various OS objects, such as file descriptors on Unix systems and handles on Windows. To do so either
use platforms specific structures such as SendableFd
or SendableWinHandle
, or cross-platform wrappers like SendableFile
. Note that though
these types implement Serialize
and Deserialize
, attempts to serialize
or deserialize
them outside of the send/receive mechanisms of a suitable IPC object
will fail.
