Struct bitvec::index::BitPos

pub struct BitPos<R = usize>where R: BitRegister,{ /* private fields */ }
Expand description

Bit Position

This is a position counter of a real bit in an R memory element.

Like BitIdx, it is a counter in the ring 0 .. R::BITS. It marks a real bit in memory, and is the shift distance in the expression 1 << n. It can only be produced by applying BitOrder::at to an existing BitIdx produced by bitvec.

Type Parameters

  • R: The register element that this position governs.

Validity

Values of this type are required to be in the range 0 .. R::BITS. Any value not less than R::BITS makes the program invalid, and will likely cause either a crash or incorrect memory access.

Construction

This type is publicly constructible, but is only correct to do so within an implementation of BitOrder::at. bitvec will only request its creation through that trait implementation, and has no sites that can publicly accept untrusted values.

Implementations§

source§

impl<R> BitPos<R>where R: BitRegister,

source

pub const MAX: Self = _

The position value of the most significant bit in an R element.

source

pub const MIN: Self = _

The position value of the least significant bit in an R element.

source

pub fn new(pos: u8) -> Option<Self>

Wraps a counter value as a known-good position within an R register.

Parameters
  • pos: The counter value to mark as a position. This must be in the range 0 .. R::BITS.
Returns

This returns Some(pos) when it is in the valid range 0 .. R::BITS, and None when it is not.

source

pub unsafe fn new_unchecked(pos: u8) -> Self

Wraps a counter value as an assumed-good position within an R register.

Parameters
  • value: The counter value to mark as a position. This must be in the range 0 .. R::BITS.
Returns

This unconditionally marks pos as a valid bit-position.

Safety

If the pos value is outside the valid range, then the program is incorrect. Debug builds will panic; release builds do not inspect the value or specify a behavior.

source

pub fn into_inner(self) -> u8

Removes the position wrapper, leaving the internal counter.

source

pub fn select(self) -> BitSel<R>

Computes the bit selector corresponding to self.

This is always 1 << self.pos.

source

pub fn mask(self) -> BitMask<R>

Computes the bit selector for self as an accessor mask.

This is a type-cast over Self::select.
