Struct libffi::high::call::Arg

source · [−]

pub struct Arg<'a> { /* private fields */ }

Expand description

Encapsulates an argument with its type information.

In order to set up calls using call, we need to wrap (a reference to) each argument in an Arg. The usual way to do this is with function arg.

Implementations

source

impl<'a> Arg<'a>

source

pub fn new<T: CType>(arg: &'a T) -> Self

Wraps an argument reference for passing to call.

For a shorter alias of the same, see arg.
