Rust compiler detecting 2 error E0599 with socket2::Type::RAW struct usage.

error[E0599]: no associated item named `RAW` found for struct `socket2::Type` in the current scope
   --> src/session.rs:135:59
    |
135 |         let send_socket = Socket::new(Domain::IPV4, Type::RAW, Some(Protocol::ICMPV4))?;
    |                                                           ^^^ associated item not found in `socket2::Type`

error[E0599]: no associated item named `RAW` found for struct `socket2::Type` in the current scope
   --> src/session.rs:138:59
    |
138 |         let recv_socket = Socket::new(Domain::IPV4, Type::RAW, Some(Protocol::ICMPV4))?;
    |                                                           ^^^ associated item not found in `socket2::Type`

To resolve the E0599 errors when using socket2::Type::RAW, we must enable all¹ feature in the Cargo.toml since the RAW socket type is not included in the default build.

Reference:

    /// Type corresponding to `SOCK_RAW`.
    #[cfg(all(feature = "all", not(any(target_os = "redox", target_os = "espidf"))))]
    #[cfg_attr(
        docsrs,
        doc(cfg(all(feature = "all", not(any(target_os = "redox", target_os = "espidf")))))
    )]
    pub const RAW: Type = Type(sys::SOCK_RAW);
