}Expand description
Abstracts common iteration operations on the input type
Required Associated Types§
sourcetype Item
type Item
The current input type is a sequence of that Item type.
Example: u8 for &[u8] or char for &str
Required Methods§
sourcefn iter_indices(&self) -> Self::Iter
fn iter_indices(&self) -> Self::Iter
Returns an iterator over the elements and their byte offsets
sourcefn iter_elements(&self) -> Self::IterElem
fn iter_elements(&self) -> Self::IterElem
Returns an iterator over the elements
Object Safety§
This trait is not object safe.
