 //! Implements C-API support for the Wasmi WebAssembly interpreter.
 //!
 //! Namely implements the Wasm C-API proposal found here: <https://github.com/WebAssembly/wasm-c-api/>
-//!
-//! # Crate features
-//!
-//! ## The `mangle-symbols` feature
-//! The `mangle-symbols` feature, when enabled, disables the `#[no_mangle]` attributes on exported symbols. This means that,
-//! when the feature is enabled, the public symbols (such as `wasm_func_new`) in this library are not visible with the
-//! plain "C" name, and the usual Rust mangling is operated instead.
-//!
-//! The rationale behind this feature is to allow (or facilitate) users that want to use multiple implementers of the
-//! C-API proposal together to avoid duplicate symbols error. This feature is disabled by default, thus public symbols
-//! are not mangled.
-//!
-//! ### Note
-//! When enabeld, the public symbols prefixed with `wasmi_` are mangled as well, even if they should not, in principle,
-//! cause any duplicate symbol error when working with other implementers.
