Struct bitvec::indices::BitPos

pub struct BitPos<T> where
    T: BitStore,  { /* private fields */ }

Indicates a real electrical index within an element.

This type is produced by BitOrder implementors, and marks a specific electrical bit within a memory element, rather than BitIdx’s semantic bit.

Type Parameters

• T: A BitStore element which provides bounds-checking information. The new constructor uses T::BITS to ensure that constructed BitPos instances are always valid to use within T elements.

Implementations

impl<T> BitPos<T> where
    T: BitStore, 

pub fn new(pos: u8) -> Self

Produce a new bit position marker at a valid position value.

BitOrder implementations should prefer this method, but may use ::new_unchecked if they can guarantee that the range invariant is upheld.

Parameters

• pos: The bit position value to encode. It must be in the range 0 .. T::BITS.

Panics

This function panics if pos is greater than or equal to T::BITS.

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

Produce a new bit position marker at any position value.

Safety

The caller must ensure that pos is less than T::BITS. BitOrder implementations should prefer ::new, which panics on range failure.

Parameters

• pos: The bit position value to encode. This must be in the range 0 .. T::BITS.

Returns

pos wrapped in the BitPos marker type.

Panics

This function panics if pos is greater than or equal to T::BITS, but only in debug builds. It does not inspect pos in release builds.
