Struct ThreadStack

#[repr(C)]
pub struct ThreadStack<const SIZE: usize> {
    pub data: UnsafeCell<[z_thread_stack_element; SIZE]>,
    /* private fields */
}

A Zephyr stack declaration.

This isn’t intended to be used directly, as it needs additional decoration about linker sections and such. Unlike the C declaration, the reservation is a separate field. As long as the SIZE is properly aligned, this should work without padding between the fields.

Generally, this should be placed in a noinit linker section to avoid having to initialize the memory.

Fields

data: UnsafeCell<[z_thread_stack_element; SIZE]>

The data of the stack itself.

Implementations

impl<const SIZE: usize> ThreadStack<SIZE>

pub const fn new() -> Self

Construct a new ThreadStack

Safety

This is unsafe as the memory remains uninitialized, and it is the responsibility of the caller to use the stack correctly. The stack should be associated with a single thread.

pub const fn size(&self) -> usize

Retrieve the size of this stack.
