#[repr(transparent)]
pub struct VaListImpl<'f> { /* private fields */ }

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

Available on non-crate feature std and (non-AArch64 and non-PowerPC and non-s390x and non-x86-64, or AArch64 and (macOS or iOS), or target_family="wasm", or JavaScript, or target_os="uefi", or Windows) only.

Basic implementation of a va_list.

Implementations

impl<'f> VaListImpl<'f>

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

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

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

impl<'f> VaListImpl<'f>

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

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

Advance to the next arg.

pub unsafe fn with_copy<F, R>(&self, f: F) -> Rwhere 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.
