Implementations§

source§

impl<'f> VaListImpl<'f>

source

pub fn as_va_list<'a>(&'a mut self) -> VaList<'a, 'f>

🔬This is a nightly-only experimental API. (c_variadic)

Converts a VaListImpl into a VaList that is binary-compatible with C’s va_list.

source§

impl<'f> VaListImpl<'f>

source

pub unsafe fn arg<T>(&mut self) -> T
where T: VaArgSafe,

🔬This is a nightly-only experimental API. (c_variadic)

Advance to the next arg.

source

pub unsafe fn with_copy<F, R>(&self, f: F) -> R
where F: for<'copy> FnOnce(VaList<'copy, 'f>) -> R,

🔬This is a nightly-only experimental API. (c_variadic)

Copies the va_list at the current location.
