Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Advances the end of the iterator, returning the last value.
The type being iterated over.
The error type.
Advances the iterator and returns the next value. Read more
Returns bounds on the remaining length of the iterator. Read more
Consumes the iterator, returning the number of remaining items.
Returns the last element of the iterator.
Returns the nth element of the iterator.
Returns an iterator starting at the same point, but stepping by the given amount at each iteration. Read more
Returns an iterator which yields the elements of this iterator followed by another. Read more
Returns an iterator that yields pairs of this iterator’s and another iterator’s values. Read more
Returns an iterator which applies a fallible transform to the elements of the underlying iterator. Read more
Calls a fallible closure on each element of an iterator.
Returns an iterator which uses a predicate to determine which values should be yielded. The predicate may fail; such failures are passed to the caller. Read more
Returns an iterator which both filters and maps. The closure may fail; such failures are passed along to the consumer. Read more
Returns an iterator which yields the current iteration count as well as the value. Read more
Returns an iterator that can peek at the next element without consuming it. Read more
Returns an iterator that skips elements based on a predicate.
Returns an iterator that yields elements based on a predicate.
Returns an iterator which skips the first n values of this iterator.
Returns an iterator that yields only the first n values of this iterator. Read more
Returns an iterator which applies a stateful map to values of this iterator. Read more
Returns an iterator which yields this iterator’s elements and ends after the first Ok(None). Read more
Borrow an iterator rather than consuming it. Read more
Transforms the iterator into a collection. Read more
Applies a function over the elements of the iterator, producing a single final value. The function may fail; such failures are returned to the caller. Read more
Determines if all elements of this iterator match a predicate. The predicate may fail; such failures are passed to the caller. Read more
Determines if any element of this iterator matches a predicate. The predicate may fail; such failures are passed to the caller. Read more
Returns the first element of the iterator that matches a predicate. The predicate may fail; such failures are passed along to the caller. Read more
Returns the position of the first element of this iterator that matches a predicate. The predicate may fail; such failures are returned to the caller. Read more
Returns the element of the iterator which gives the maximum value from the function. The function may fail; such failures are returned to the caller. Read more
Returns the element of the iterator which gives the minimum value from the function. The function may fail; such failures are returned to the caller. Read more
Returns an iterator which clones all of its elements.
Lexicographically compares the elements of this iterator to that of another. Read more
Determines if the elements of this iterator are equal to those of another. Read more
Determines if the elements of this iterator are not equal to those of another. Read more
Determines if the elements of this iterator are lexicographically less than those of another. Read more
Determines if the elements of this iterator are lexicographically less than or equal to those of another. Read more
Determines if the elements of this iterator are lexicographically greater than those of another. Read more
Determines if the elements of this iterator are lexicographically greater than or equal to those of another. Read more
Returns a normal (non-fallible) iterator over Result<Item, Error>.
Returns an iterator which applies a transform to the errors of the underlying iterator. Read more
