mtls only.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
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
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
