no_std support

[bahlo]

Would be amazing to be able to use this on embedded devices, for that we need no_std support though.

Hey! Sorry it went quiet here.

The implemented IP transport relies heavily on tokio, so I don't see it working without a std net implementation or an OS-specific I/O driver anytime soon.

BLE transport could be a different story tho, should we manage to implement it at some point and feature-gate the IP part away. No timeline on it yet, but happy about contributions.

What's your embedded target platform?

Hey, no worries! Not decided yet, probably cortex-m. Would be amazing to do embedded devices with native HomeKit support all written in Rust.

I'm also interested in getting something like embedded nordic's nRF (arm, well supported), espressif esp32 (rust fork needed tor xtensa arch here), bl602 (risc-v, compilation supported, need drivers/PAC crates) homekit device programmed in Rust.

For embedded networking we may use smoltcp (rust) or lwip (C, which we need to link against) - depending on the chip/sdk

There are also libraries like rust-embedded-community/embedded-nal that should hopefully make it easier.
