# Shared Bit-Slice Iteration
This view iterates each bit in the bit-slice by [proxy reference][0]. It is
created by the [`BitSlice::iter`] method.
## Original
[`slice::Iter`](core::slice::Iter)
## API Differences
While this iterator can manifest `&bool` references, it instead yields the
`bitvec` [proxy reference][0] for consistency with the [`IterMut`] type. It can
be converted to yield true references with [`.by_refs()`]. Additionally, because
it does not yield `&bool`, the [`Iterator::copied`] method does not apply. It
can be converted to an iterator of `bool` values with [`.by_vals()`].
## Examples
```rust
use bitvec::prelude::*;
let bits = bits![0, 1];
for bit in bits.iter() {
# #[cfg(feature = "std")] {
println!("{}", bit);
# }
}
```
