Struct std::ffi::VaList
#[repr(transparent)]pub struct VaList<'a, 'f> where 'f: 'a, { /* private fields */ }
A wrapper for a va_list
Methods from Deref<Target = VaListImpl<'f>>
pub fn as_va_list(&'a mut self) -> VaList<'a, 'f>
Convert a VaListImpl
into a VaList
that is binary-compatible with C’s va_list
.
Trait Implementations
impl<'a, 'f> Debug for VaList<'a, 'f> where
'f: 'a,
fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl<'a, 'f> Deref for VaList<'a, 'f> where
'f: 'a,
type Target = VaListImpl<'f>
The resulting type after dereferencing.
fn deref(&self) -> &VaListImpl<'f>
Dereferences the value.
impl<'a, 'f> DerefMut for VaList<'a, 'f> where
'f: 'a,
