Implementations

impl<'a> CArg

fn arg_downcast(&'a self) -> Arg<'a>

Convert a CArg to a libffi argument type.

Trait Implementations

impl Clone for CArg

fn clone(&self) -> CArg

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CArg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
