Tracking Issue for const Cell methods that depend on const traits (original) (raw)

Feature gate: #![feature(const_cell_traits)]

This is a tracking issue for const Cell methods that depend on const traits.

Public API

impl Cell { pub const fn set(&self, val: T) where T: [const] Destruct;

// NOTE: Copy should imply const Destruct, but it doesn't atm
pub const fn update(&self, f: impl [const] FnOnce(T) -> T) where T: Copy + [const] Destruct;

pub const fn take(&self) -> T where T: [const] Default;

}
