Overview ¶
Package stateless defines a stateless (pure) iterator, i.e. one that can be iterated over multiple times without side effects, it is threadsafe

Functions ¶
func Compress ¶ added in v1.0.13
Compress returns an Iterator that filters elements from a data Iterator returning only those that have a corresponding element in selector Iterator that evaluates to `true`. Stops when either the data or selectors iterator has been exhausted.
func DropWhile ¶ added in v1.0.13
DropWhile creates an Iterator that drops elements from the Iterator as long as the predicate is true; afterwards, returns every element. Note, the Iterator does not produce any output until the predicate first becomes false
func Map ¶
Map transforms an Iterator of type [U] into an Iterator of type [V] via a mapping function
func Scan ¶ added in v1.0.12
Scan takes an Iterator and returns a new Iterator of the same length, where the values of the new Iterator are the result of the application of `f` to the value of the source iterator with the previously accumulated value
Types ¶
type Iterator ¶
Iterator represents a stateless, pure way to iterate over a sequence
func Count ¶ added in v1.0.13
Count creates an Iterator containing a consecutive sequence of integers starting with the provided start value
func Cycle ¶ added in v1.0.13
DropWhile creates an Iterator that drops elements from the Iterator as long as the predicate is true; afterwards, returns every element. Note, the Iterator does not produce any output until the predicate first becomes false
func MakeBy ¶
MakeBy returns an Iterator with an infinite number of elements initialized with `f(i)`
func MonadMap ¶
MonadMap transforms an Iterator of type [U] into an Iterator of type [V] via a mapping function
func Repeat ¶ added in v1.0.13
Repeat creates an Iterator containing a value repeated the specified number of times. Alias of Replicate
func Replicate ¶
Replicate creates an Iterator containing a value repeated an infinite number of times.
func StrictUniq ¶ added in v1.0.11
func StrictUniq[A comparable](as Iterator[A]) Iterator[A]
StrictUniq converts an Iterator or arbitrary items into an Iterator or unique items where uniqueness is determined by the built-in uniqueness constraint
