pub struct Context { /* private fields */ }
Expand description
Handle for a 0MQ context, used to create sockets.
It is thread safe, and can be safely cloned and shared. Each clone
references the same underlying C context. Internally, an Arc
is
used to implement this in a threadsafe way.
Also note that this binding deviates from the C API in that each
socket created from a context initially owns a clone of that
context. This reference is kept to avoid a potential deadlock
situation that would otherwise occur:
Destroying the underlying C context is an operation which
blocks waiting for all sockets created from it to be closed
first. If one of the sockets belongs to thread issuing the
destroy operation, you have established a deadlock.
You can still deadlock yourself (or intentionally close sockets in
other threads, see zmq_ctx_destroy
(3)) by explicitly calling
Context::destroy
.
Create a new reference-counted context handle.
Create a new socket.
Note that the returned socket keeps a an Arc
reference to
the context it was created from, and will keep that context
from being dropped while being live.
Try to destroy the context. This is different than the destructor; the
destructor will loop when zmq_ctx_destroy returns EINTR.
