[−][src]Enum bitvec::domain::BitDomain
Granular representation of the memory region containing a
BitSlice
.
BitSlice
regions can be described in terms of edge and center
elements, where the edge elements retain the aliasing status of the
source BitSlice
handle, and the center elements are known to be
completely unaliased by any other view. This property allows any
BitSlice
handle to be decomposed into smaller regions, and safely
remove any aliasing markers from the subregion of memory that no
longer requires them for correct access.
This enum acts like the .split*
methods in that it only subdivides
the source BitSlice
into smaller BitSlices
, and makes
appropriate modifications to the aliasing markers. It does not
provide references to the underlying memory elements. If you need
such access directly, use the Domain
or DomainMut
enums.
Lifetimes
'a
: The lifetime of the referent storage region.
Type Parameters
O
: The ordering type of the sourceBitSlice
handle.T
: The element type of the sourceBitSlice
handle, including aliasing markers.
Aliasing Awareness
This enum does not grant access to memory outside the scope of the
original &BitSlice
handle, and so does not need to modfiy any
aliasing conditions.
Variants
Indicates that a BitSlice
is contained entirely in the
interior indices of a single memory element.
Fields of Enclave
head: BitIdx<T::Mem>
The start index of the BitSlice
.
This is not likely to be useful information, but is retained for structural similarity with the rest of the module.
body: &'a BitSlice<O, T>
The original BitSlice
used to create this bit-domain view.
tail: BitTail<T::Mem>
The end index of the BitSlice
.
This is not likely to be useful information, but is retained for structural similarity with the rest of the module.
Indicates that a BitSlice
region touches at least one edge
index of any number of elements.
This contains two bitslices representing the partially-occupied edge elements, with their original aliasing marker, and one bitslice representing the fully-occupied interior elements, marked as unaliased.
Fields of Region
head: &'a BitSlice<O, T>
Any bits that partially-fill the base element of the slice region.
This does not modify its aliasing status, as it will already be appropriately marked before constructing this view.
body: &'a BitSlice<O, T::Mem>
Any bits inside elements that the source bitslice completely covers.
This is marked as unaliased, because it is statically impossible for any other handle to have write access to the region it covers. As such, a bitslice that was marked as entirely aliased, but contains interior unaliased elements, can safely remove its aliasing protections.
tail: &'a BitSlice<O, T>
Any bits that partially fill the last element of the slice region.
This does not modify its aliasing status, as it will already be appropriately marked before constructing this view.
Implementations

[src]
self
) -> Option<(BitIdx<T::Mem>, &'a BitSlice<O, T>, BitTail<T::Mem>)>
Attempts to view the domain as an enclave variant.
Parameters
self
Returns
If self
is the Enclave
variant, this returns Some
of the
enclave fields, as a tuple. Otherwise, it returns None
.
pub fn region(
self
) -> Option<(&'a BitSlice<O, T>, &'a BitSlice<O, T::Mem>, &'a BitSlice<O, T>)>
[src]
self
) -> Option<(&'a BitSlice<O, T>, &'a BitSlice<O, T::Mem>, &'a BitSlice<O, T>)>
Attempts to view the domain as a region variant.
Parameters
self
Returns
If self
is the Region
variant, this returns Some
of the
region fields, as a tuple. Otherwise, it returns None
.
