Trait binaryen::ToCStr

pub trait ToCStr {
    type Storage;
    fn to_cstr_stash(self) -> Stash<Self::Storage>;
}

This trait provides a means for converting various types of strings into a pointer that can be passed into C code.

If you have a CString/&CStr you can use it to pass a C string pointer directly, without conversion. Otherwise, you can sacrifice your String to convert it into CString.

Required Methods

fn to_cstr_stash(self) -> Stash<Self::Storage>

Make conversion to a C string (if needed) and then return a Stash — a pointer to the C string alongside with a storage which "owns" the data it points to.
