Part of the Cotton project.
Enumerating network interfaces and their IP addresses
The cotton-netif library crate encapsulates the obtaining of the host’s network interfaces and IP addresses. It supports both static/synchronous listing (i.e., a snapshot of the current list of network interfaces) using getinterfaces and dynamic/asynchronous listing (i.e., getting events as network interfaces and addresses come and go) using getinterfaces_async.
At present this crate only works on Linux (and maybe BSD) but the structure is such that adding compatibility with other platforms in future, shouldn’t require changes to any client code.
Library documentation is on docs.rs.
