pub struct BitMask<R = usize>where
R: BitRegister,{ /* private fields */ }
Expand description
§Multi-Bit Selection Mask
Unlike BitSel
, which enforces a strict one-hot mask encoding, this type
permits any number of bits to be set or cleared. This is used to accumulate
selections for batched operations on a register in real memory.
§Type Parameters
R
: The register element that this mask governs.
§Construction
This must only be constructed by combining BitSel
selection masks produced
through the accepted chains of custody beginning with BitIdx
values.
Bit-masks not constructed in this manner are not guaranteed to be correct in the
caller’s context and may lead to incorrect memory behaviors.
Implementations§
Source§impl<R> BitMask<R>where
R: BitRegister,
impl<R> BitMask<R>where
R: BitRegister,
Sourcepub fn new(mask: R) -> Self
pub fn new(mask: R) -> Self
Wraps any R
value as a bit-mask.
This constructor is provided to explicitly declare that an operation is discarding the numeric value of an integer and instead using it only as a bit-mask.
§Parameters
mask
: Some integer to use as a bit-mask.
§Returns
The mask
value wrapped as a bit-mask, with its numeric context
discarded.
Prefer accumulating BitSel
values using its Sum
implementation.
§Safety
The mask
value must be computed from a set of valid bit positions in
the caller’s context.
Sourcepub fn into_inner(self) -> R
pub fn into_inner(self) -> R
Removes the mask wrapper, leaving the internal value.
