HramAtomicCell

gb::hram

Struct HramAtomicCell 

Source 
pub struct HramAtomicCell<T>(/* private fields */)
where
    T: CellValue;
Expand description

Storage for a one-byte cell, accessed without a CriticalSection.

Declare it with hram!; the accessors live on the handle that macro generates, not on this type. A wider type is a compile error.

Implementations§

Source§

impl<T> HramAtomicCell<T>
where T: CellValue,

Source

pub const unsafe fn uninit() -> HramAtomicCell<T>

Reserve a cell.

§Safety

The cell must come to rest at an address in 0xFF80..=0xFFFE. hram! guarantees this; a hand-placed cell needs #[link_section = "_HRAM.*"].

Source

pub const fn ptr(&self) -> *mut T

The cell’s address as a raw pointer.
