Expand description
Abstracts common iteration operations on the input type
Associated Types
The current input type is a sequence of that Item
type.
Example: u8
for &[u8]
or char
for &str
An iterator over the input type, producing the item and its position
for use with Slice. If we’re iterating over &str
, the position
corresponds to the byte index of the character
Required methods
fn iter_indices(&self) -> Self::Iter
fn iter_indices(&self) -> Self::Iter
Returns an iterator over the elements and their byte offsets
fn iter_elements(&self) -> Self::IterElem
fn iter_elements(&self) -> Self::IterElem
Returns an iterator over the elements
Finds the byte position of the element
