Enum hs_bindgen_traits::HsType

pub enum HsType {
    CString,
    Empty,
    IO(Box<HsType>),
}

Enumeration of all Haskell F-FFI safe types as the string representation of their token in Haskell.

Variants

CString

Empty

IO(Box<HsType>)

Implementations

impl HsType

pub fn quote(&self) -> TokenStream

Get the C-FFI Rust type that match the memory layout of a given HsType.

This function return a OUTPUT: proc_macro2::TokenStream that should be valid (considered as FFI-safe by rustc) in the context of a block of form: quote! { extern C fn _(_: #OUTPUT) {} }
