Methods

tryCollect() → Result<List<T>, E>

Transforms an iterator into a collection, short circuiting if a Err is encountered.

tryFind(bool f(T)) → Result<Option<T>, E>

Applies function to the elements of iterator and returns the first true result or the first Err element.

tryFold<U>(U initial, U f(U, T)) → Result<U, E>

An iterator method that applies a function producing a single value, returns Err is encounted.

tryForEach(void f(T)) → Result<(), E>

An iterator method that applies a function, stopping at the first Err and returning that Err.

tryReduce(T f(T, T)) → Result<Option<T>, E>

Reduces the elements to a single one by repeatedly applying a reducing operation. If a Err is encounted it is returned.
