§Bit-Slice Element Partitioning

This structure provides the bridge between bit-precision memory modeling and element-precision memory manipulation. It allows a bit-slice to provide a safe and correct view of the underlying memory elements, without exposing the values, or permitting mutation, of bits outside a bit-slice’s control but within the elements the bit-slice uses.

Nearly all memory access that is not related to single-bit access goes through this structure, and it is highly likely to be in your hot path. Its code is a perpetual topic of optimization, and improvements are always welcome.

This is essentially a fully-decoded BitSpan handle, in that it addresses memory elements directly and contains the bit-masks needed to selectively interact with them. It is therefore by necessity a large structure, and is usually only alive for a short time. It has a minimal API, as most of its logical operations are attached to BitSlice, and merely route through it.

If your application cannot afford the cost of repeated Domain construction, please file an issue.

§Memory Model and Variants

A given BitSlice has essentially two possibilities for where it resides in real memory:

  • it can reside entirely in the interior of a exactly one memory element, touching neither edge bit, or
  • it can touch at least one edge bit of zero or more elements.

These states correspond to the Enclave and Region variants, respectively.

When a BitSlice has only partial control of a given memory element, that element can only be accessed through the bit-slice’s provenance by a PartialElement handle. This handle is an appropriately-guarded reference to the underlying element, as well as mask information needed to interact with the raw bits and to manipulate the numerical contents. Each PartialElement guard carries permissions for its own bits within the guarded element, independently of any other handle that may access the element, and all handles are appropriately synchronized with each other to prevent race conditions.

The Enclave variant is a single PartialElement. The Region variant is more complex. It has:

  1. an optional PartialElement for the case where the bit-slice only partially occupies the lowest-addressed memory element it governs, starting after bit-index 0 and extending up to the maximal bit-index,
  2. a slice of zero or more fully-occupied memory elements,
  3. an optional PartialElement for the case where it only partially occupies the highest-addressed memory element it governs, starting at bit-index 0 and ending before the maximal.

§Usage

Once created, match upon a Domain to access its fields. Each PartialElement has a .load_value() method that produces its stored value (with all ungoverned bits cleared to 0), and a .store_value() that writes into its governed bits. If present, the fully-occupied slice can be used as normal.

Variants§

§

Enclave(PartialElement<'a, M, T, O>)

Indicates that a bit-slice’s contents are entirely in the interior indices of a single memory element.

The contained reference is only able to observe the bits governed by the generating bit-slice. Other handles to the element may exist, and may write to bits outside the range that this reference can observe.

§

Region

Indicates that a bit-slice’s contents touch an element edge.

This splits the bit-slice into three partitions, each of which may be empty: two partially-occupied edge elements, with their original type status, and one interior span, which is known not to have any other aliases derived from the bit-slice that created this view.

Fields

§head: Option<PartialElement<'a, M, T, O>>

The first element in the bit-slice’s underlying storage, if it is only partially used.

§body: <Address<M, [<T as BitStore>::Unalias]> as Referential<'a>>::Ref

All fully-used elements in the bit-slice’s underlying storage.

This is marked as unaliased, because it is statically impossible for any other handle derived from the source bit-slice to have conflicting access to the region of memory it describes. As such, even a bit-slice that was marked as ::Alias can revert this protection on the known-unaliased interior.

§tail: Option<PartialElement<'a, M, T, O>>

The last element in the bit-slice’s underlying storage, if it is only partially used.

Implementations§

source§

impl<'a, M, T, O> Domain<'a, M, T, O>
where M: Mutability, T: 'a + BitStore, O: BitOrder, Address<M, T>: Referential<'a>, Address<M, [<T as BitStore>::Unalias]>: SliceReferential<'a>,

source

pub fn enclave(self) -> Option<PartialElement<'a, M, T, O>>

Attempts to unpack the bit-domain as an Enclave variant. This is just a shorthand for explicit destructuring.

source

pub fn region( self ) -> Option<(Option<PartialElement<'a, M, T, O>>, <Address<M, [<T as BitStore>::Unalias]> as Referential<'a>>::Ref, Option<PartialElement<'a, M, T, O>>)>

Attempts to unpack the bit-domain as a Region variant. This is just a shorthand for explicit destructuring.

source

pub fn into_bit_domain(self) -> BitDomain<'a, M, T, O>
where Address<M, BitSlice<T, O>>: Referential<'a>, Address<M, BitSlice<<T as BitStore>::Unalias, O>>: Referential<'a>, <Address<M, BitSlice<T, O>> as Referential<'a>>::Ref: Default, <Address<M, BitSlice<<T as BitStore>::Unalias, O>> as Referential<'a>>::Ref: TryFrom<<Address<M, [<T as BitStore>::Unalias]> as Referential<'a>>::Ref>,

Converts the element-wise Domain into the equivalent BitDomain.

This transform replaces each memory reference with an equivalent BitSlice reference.

This impl block contains no items.

Domain constructors.

Only Domain<Const> and Domain<Mut> are ever constructed, and they of course are only constructed from &BitSlice and &mut BitSlice, respectively.

However, the Rust trait system does not have a way to express a closed set, so
