Struct secgate::Return

source ·
#[repr(C)]
pub struct Return<T: Crossing + Copy> { /* private fields */ }
Expand description

Return value to be filled by the secure call. Concrete versions of this are generated by the macro.

Implementations§

source§

impl<T: Crossing + Copy> Return<T>

source

pub fn with_alloca<F, R>(f: F) -> Rwhere F: FnOnce(&mut Self) -> R,

source

pub fn into_inner(self) -> Option<T>

If a previous call to set is made, or this was constructed by new(), then into_inner returns the inner value. Otherwise, returns None.

source

pub fn new_uninit() -> Self

Construct a new, uninitialized Self.

source

pub fn set(&mut self, val: T)

Set the inner value. Future call to into_inner will return Some(val).
