[−][src]Trait glsp_engine::MakeArg

pub trait MakeArg<'a>: Sized + MakeTemp {
    fn make_arg(temp: &'a mut Self::Temp) -> GResult<Self>;
}

A type which can act as an RFn parameter.

A blanket implementation is provided for any type which implements FromVal, and also for several other types:

  • Option<T>, which acts as an optional parameter, storing None when an argument isn't provided.
  • &[T] or &mut [T], which act as a "rest" parameter, capturing any number of arguments.
  • OrNil<T>, which accepts either the specified type or #n.
  • Shared references to primitive types: &Arr, &Tab, etc.
  • String slices: &str, &Path, &CStr, &OsStr.
  • &T and &mut T, where T was defined using the lib! or rdata! macros.

It's not possible to implement this trait for your own types. Implement FromVal instead, or define your type using rdata! or lib!.
