Struct Stack

Source 
#[repr(C, align(16))]
pub struct Stack<const SIZE: usize> {
    pub mem: MaybeUninit<[u8; SIZE]>,
}
Available on crate feature unstable only.
Expand description

Data type for a properly aligned stack of N bytes

§Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Fields§

§mem: MaybeUninit<[u8; SIZE]>

Memory to be used for the stack
