Rust smoltcp 0.12 staticlib + C FFI for the esp_smoltcp ESP-IDF component.
readme
# esp_smoltcp_glue Rust [smoltcp](https://github.com/smoltcp-rs/smoltcp) 0.12 packaged as an ESP-IDF component — `no_std` staticlib for `riscv32imafc-unknown-none-elf` plus a small C FFI. You don't usually depend on this directly; depend on [`datanoisetv/esp_smoltcp`](https://components.espressif.com/components/datanoisetv/esp_smoltcp) instead, which pulls this in. Full docs and architecture: https://github.com/DatanoiseTV/esp-smoltcp ## What's in it - smoltcp 0.12 IPv4 + IPv6 (link-local), DHCPv4 client, ICMP/ICMPv6, IGMPv2/MLD multicast, TCP + UDP sockets - C FFI exposing the smoltcp interface to the rest of the stack - Static TX scratch pool (16 × 1.5 KiB) to avoid per-packet allocations - Two-tier allocator: internal SRAM first, PSRAM fallback ## Build requirements - ESP-IDF v5.4 or later - Rust nightly with `rust-src` and the `riscv32imafc-unknown-none-elf` target. The pinned channel lives in `rust-toolchain.toml` and rustup picks it up automatically. ## License Apache-2.0 OR MIT, your choice.
