Expand description
Partially-Owned Memory Element
This type is a guarded reference to memory that permits interacting with it as
an integer, but only allows views to the section of the integer that the
producing handle has permission to observe. Unlike the BitSafe
type family in
the access
module, it is not a transparent wrapper that can be used for
reference conversion; it is a “heavy reference” that carries the mask and
Type Parameters
T
: The type, including register width and alias information, of the bit-slice handle that created it.O
: This propagates the bit-ordering type used by theBitSlice
handle that created it.
Lifetime
This carries the lifetime of the bit-slice handle that created it.
Usage
This structure is only created as part of the Domain
region descriptions,
and refers to partially-occupied edge elements. The underlying referent memory
can be read with .load_value()
or written with .store_value()
, and the
appropriate masking will be applied in order to restrict access to only the
permitted bits.
Implementations
impl<'a, M, T, O> PartialElement<'a, M, T, O> where
M: Mutability,
T: 'a + BitStore,
O: BitOrder,
impl<'a, M, T, O> PartialElement<'a, M, T, O> where
M: Mutability,
T: 'a + BitStore,
O: BitOrder,
Fetches the value stored through self
and masks away extra bits.
Returns
A bit-map containing any bits set to 1
in the governed bits. All other
bits are cleared to 0
.
Gets the semantic head and tail indices that constrain which bits of the referent element may be accessed.
pub fn into_bitslice(self) -> Reference<'a, M, BitSlice<T, O>> where
Address<M, BitSlice<T, O>>: Referential<'a>,
pub fn into_bitslice(self) -> Reference<'a, M, BitSlice<T, O>> where
Address<M, BitSlice<T, O>>: Referential<'a>,
Converts the partial element into a bit-slice over its governed bits.
impl<'a, T, O> PartialElement<'a, Mut, T, O> where
T: BitStore,
O: BitOrder,
Address<Mut, T>: Referential<'a>,
impl<'a, T, O> PartialElement<'a, Mut, T, O> where
T: BitStore,
O: BitOrder,
Address<Mut, T>: Referential<'a>,
Stores a value through self
after masking away extra bits.
Parameters
&mut self
value
: A bit-map which will be written into the governed bits. This is a bit-map store, not an integer store; the value will not be shifted into position and will only be masked directly against the bits that this partial-element governs.
Returns
The previous value of the governed bits.
Inverts the value of each bit governed by the partial-element.
Returns
The previous value of the governed bits.
Clears all bits governed by the partial-element to 0
.
Returns
The previous value of the governed bits.

impl<'a, M, T, O> PartialElement<'a, M, T, O> where
M: Mutability,
O: BitOrder,
