[−][src]Struct bitvec::index::BitIdx
A semantic index of a single bit within a register R
.
This type is a counter in the range 0 .. R::BITS
, and marks the semantic
position of a bit according to some BitOrder
implementation. As an abstract
counter, it can be used in arithmetic without having to go through BitOrder
translation to an electrical position.
Type Parameters
R
: The register type that these values govern.
Validity
Values of this type are required to be in the range 0 .. R::BITS
. Any value
outside this range will cause the program state to become invalid, and the
library’s behavior is unspecified. The library will never produce such an
invalid value.
Construction
This type cannot be constructed outside the bitvec
crate. bitvec
will
construct safe values of this type, and allows users to view them and use them
to construct other index types from them. All values of this type constructed by
bitvec
are known to be correct based on user input to the crate.
Implementations
impl<R> BitIdx<R> where
R: BitRegister,
[src]
R: BitRegister,
pub fn position<O>(self) -> BitPos<R> where
O: BitOrder,
[src]
O: BitOrder,
Computes the bit position corresponding to self
under some ordering.
This forwards to O::at::<R>
, and is the only public, safe, constructor
for a position counter.
pub fn select<O>(self) -> BitSel<R> where
O: BitOrder,
[src]
O: BitOrder,
Computes the bit selector corresponding to self
under an ordering.
This forwards to O::select::<R>
, and is the only public, safe,
constructor for a bit selector.
pub fn mask<O>(self) -> BitMask<R> where
O: BitOrder,
[src]
O: BitOrder,
Computes the bit selector for self
as an accessor mask.
This is a type-cast over Self::select
. It is one of the few public,
safe, constructors of a multi-bit mask.
pub fn value(self) -> u8
[src]
Views the internal index value.
pub fn range(
from: Self,
upto: BitTail<R>
) -> impl Iterator<Item = Self> + DoubleEndedIterator + ExactSizeIterator + FusedIterator
[src]
from: Self,
upto: BitTail<R>
) -> impl Iterator<Item = Self> + DoubleEndedIterator + ExactSizeIterator + FusedIterator
Constructs a range over all indices between a start and end point.
Because implementation details of the RangeOps
family are not yet
stable, and heterogenous ranges are not supported, this must be an
opaque iterator rather than a direct Range<BitIdx<R>>
.
Parameters
from
: The inclusive low bound of the range. This will be the first index produced by the iterator.upto
: The exclusive high bound of the range. The iterator will halt before yielding an index of this value.
Returns
An opaque iterator that is equivalent to the range from .. upto
.
Requirements
from
must be no greater than upto
.
