pub struct BitSafeUsize { /* private fields */ }
Expand description
§Read-Only Shared-Mutable Handle
This type marks a handle to a shared-mutable type that may be modified through
other handles, but cannot be modified through this one. It is used when a
BitSlice
region has partial ownership of an element and wishes to expose the
entire underlying raw element to the user without granting them write
permissions.
Under the feature = "atomic"
build setting, this uses radium
’s best-effort
atomic alias; when this feature is disabled, it reverts to Cell
.

All implementors are required to have their alignment match their size. Read more
Source§const ALIAS_WIDTH: [(); 1] = _
const ALIAS_WIDTH: [(); 1] = _
All implementors are required to have
Self
and Self::Alias
be equal
in representation. This is true by fiat for all types except the
unsigned integers. Read moreSource§type Mem = usize
type Mem = usize
The element type used in the memory region underlying a
BitSlice
. It
is always one of the unsigned integer fundamentals.Source§type Access = <BitSafeUsize as BitSafe>::Rad
type Access = <BitSafeUsize as BitSafe>::Rad
A type that selects the appropriate load/store instructions when
accessing the memory bus. It determines what instructions are used when
moving a
Self::Mem
value between the processor and the memory system. Read moreSource§type Alias = BitSafeUsize
type Alias = BitSafeUsize
A sibling
BitStore
implementor that is known to be alias-safe. It is
used when a BitSlice
introduces multiple handles that view the same
memory location, and at least one of them has write capabilities to it.
It must have the same underlying memory type, and can only change access
patterns or public-facing usage.Source§type Unalias = usize
type Unalias = usize
The inverse of
::Alias
. It is used when a BitSlice
removes the
conditions that required a T -> T::Alias
transition.Source§fn load_value(&self) -> Self::Mem
fn load_value(&self) -> Self::Mem
Loads a value out of the memory system according to the
::Access
rules. This may be called when the value is aliased by a write-capable
reference.Source§fn store_value(&mut self, value: Self::Mem)
fn store_value(&mut self, value: Self::Mem)
Stores a value into the memory system. This is only called when there
are no other handles to the value, and it may bypass
::Access
constraints.Auto Trait Implementations§
