Struct TaskLocalCell 

Source 
pub struct TaskLocalCell<T>(/* private fields */);
Expand description

A cell for static storage in single-task cFS apps.

Provides &mut T access without runtime overhead. Only sound when the static is accessed by a single cFS task.

Implementations§

Source§

impl<T> TaskLocalCell<T>

Source

pub const fn new(val: T) -> Self

Creates a new cell with the given value.

Source

pub fn get_mut(&self) -> &mut T

Returns a mutable reference to the inner value.

§Safety contract

The caller must ensure that only one cFS task accesses this cell. This is guaranteed by default for any static inside a single cFS app’s .so.
