Module rust_corosync::cpg [−][src]
Expand description
cpg is the Control Process Groups subsystem of corosync and is usually used for sending messages around the cluster. All processes using CPG belong to a named group (whose members they can query) and all messages are sent with delivery guarantees.
Structs
A CPG address entry returned in the callbacks
struct returned from iterating over a CpgIterStart
An object to iterate over a list of CPG groups, create one of these and then use ‘for’ over it
A handle into the cpg library. Returned from initialize and needed for all other calls
Data for model1 initialize
RingId returned by totem_confchg_fn
Enums
Type of iteration for CpgIterStart
Flow control state returned from flow_control_state_get
Totem delivery guarantee options for mcast_joined
No flags current specified for model1 so leave this at None
Modeldata for initialize, only v1 supported at the moment
Reason for cpg item callback
Functions
Get the current ‘context’ value for this handle. The context value is an arbitrary value that is always passed back to callbacks to help identify the source
Set the current ‘context’ value for this handle. The context value is an arbitrary value that is always passed back to callbacks to help identify the source. Normally this is set in initialize, but this allows it to be changed
Call any/all active CPG callbacks for this Handle see DispatchFlags for details
Returns a file descriptor to use for poll/select on the CPG handle
Finish with a connection to corosync
Get the flow control state of corosync CPG
Initialize a connection to the cpg library. You must call this before doing anything else and use the passed back Handle. Remember to free the handle using finalize when finished.
Joins a CPG group for sending and receiving messages
Leave the currently joined CPG group, another group can now be joined on the same Handle or finalize can be called to finish using CPG
Get the local node ID
Get the maximum size that CPG can send in one corosync message, any messages sent via mcast_joined that are larger than this will be fragmented
Send a message to the currently joined CPG group
Get a list of members of a CPG group as a vector of Address structs
