-/// Macro to implement `NixDeserialize` on a type.
-/// Sometimes you can't use the deriver to implement `NixDeserialize`
-/// (like when dealing with types in Rust standard library) but don't want
-/// to implement it yourself. So this macro can be used for those situations
-/// where you would derive using `#[nix(from_str)]`,
-/// `#[nix(from = "FromType")]` or `#[nix(try_from = "FromType")]` if you
-/// could.
-///
-/// #### Example
-///
-/// ```rust
-/// # use nix_compat_derive::nix_deserialize_remote;
-/// #
-/// struct MyU64(u64);
-///
-/// impl From<u64> for MyU64 {
-///     fn from(value: u64) -> Self {
-///         Self(value)
-///     }
-/// }
-///
-/// nix_deserialize_remote!(#[nix(from="u64")] MyU64);
-/// ```
