Cargo Features

[dependencies]
esp-wifi = { version = "0.11.0", default-features = false, features = ["esp-alloc", "esp32c2", "esp32c3", "esp32c6", "esp32h2", "esp32", "esp32s2", "esp32s3", "coex", "sys-logs", "defmt", "log", "wifi", "esp-now", "sniffer", "ble", "smoltcp", "utils", "serde"] }

default = esp-alloc

The esp-alloc feature is set by default whenever esp-wifi is added without default-features = false somewhere in the dependency tree.

esp-alloc default

Use esp-alloc for dynamic allocations.

If you opt-out you need to provide implementations for pub extern "C" fn esp_wifi_free_internal_heap() -> usize and pub extern "C" fn esp_wifi_allocate_from_internal_ram(size: usize) -> *mut u8

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
