This crate provides DynPhy
, DynTxToken
, and DynRxToken
, which are object-safe versions
of smoltcp
's phy::Device
, phy::RxToken
, and phy::TxToken
.
These Dyn*
types are fully-compatible with and blanket-impled over the smoltcp
types. They are
unfortunately only optimistically zero-alloc (i.e. they may allocate depending on closure sizes).
Examples
The motivating use-case for this functionality is dynamic dispatch over multiple PHY interfaces, e.g. for packet-switching. This crate makes the following possible:
use dyn_phy::DynPhy;
use smoltcp::phy;
let mut loopback = phy::Loopback::new(phy::Medium::Ethernet);
let mut fault_test = phy::FaultInjector::new(phy::Loopback::new(phy::Medium::Ethernet), 0);
// This would not be possible with phy::Device as it is not object-safe:
let mut devs = heapless::Vec::<&mut dyn DynPhy, 8>::new();
devs.push(&mut loopback);
devs.push(&mut fault_test);
for dev in &mut devs {
println!("{:?}", dev.capabilities());
}
