Enum nng::options::MaxTtl [−][src]
pub enum MaxTtl {}
Expand description
The maximum number of “hops” a message may traverse.
The intention here is to prevent forwarding loops in device chains. Note that not all protocols support this option and those that do generally have a default value of 8.
Each node along a forwarding path may have its own value for the maximum time-to-live, and performs its own checks before forwarding a message. Therefore it is helpful if all nodes in the topology use the same value for this option.
Support
- Sockets can use this with the following protocols:
- Pair v1
- Rep v0
- Req v0
- Surveyor v0
- Respondent v0
- Dialers and Listeners can retrieve it from their owning Socket, if applicable.
