// Required methods
fn iter_indices(&self) -> Self::Iter;
fn iter_elements(&self) -> Self::IterElem;

}Expand description
Abstracts common iteration operations on the input type
Required Associated Types§
type Item
type Item
The current input type is a sequence of that Item type.
Example: u8 for &[u8] or char for &str
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
fn slice_index(&self, count: usize) -> Result<usize, Needed>
fn slice_index(&self, count: usize) -> Result<usize, Needed>
Get the byte offset from the element’s position in the stream
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
