Struct ink_storage::collections::bitvec::ChunkRef

#[repr(C)]pub struct ChunkRef<T> { /* fields omitted */ }

A reference to a subslice within a 256-bit chunk.

This is a reference wrapper around either a shared 256-bit chunk or an exclusive 256-bit chunk. Also it prevents accesses to out of bounds bits.

Implementations

impl<T> ChunkRef<T>

pub fn len(&self) -> u32

Returns the length of the 256-bit chunk.

Note

This is the number of valid bits in the chunk of 256 bits. The valid bits are consecutive and always start from index 0.

impl<'a> ChunkRef<&'a Bits256>

pub fn position_first_zero(&self) -> Option<u8>

Returns the position of the first valid zero bit if any.

pub fn get(&self, index: u8) -> Option<bool>

Returns the value of the indexed bit.

Note

• If 0: returns false
• If 1: returns true

impl<'a> ChunkRef<&'a mut Bits256>

pub fn get_mut(&mut self, index: u8) -> Option<BitRefMut<'_>>

Returns mutable access to a single bit if the index is out of bounds.

Trait Implementations

impl<T: Clone> Clone for ChunkRef<T>

fn clone(&self) -> ChunkRef<T>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Copy> Copy for ChunkRef<T>

impl<T: Debug> Debug for ChunkRef<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Deref for ChunkRef<&'a mut Bits256>

type Target = ChunkRef<&'a Bits256>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
