Add lazyCache to std.algorithm.iteration
|
|
|
|
The new `lazyCache` function provides a lazily evaluated range caching mechanism.
|
|
Unlike `cache`, which eagerly evaluates range elements during construction,
|
|
`lazyCache` defers evaluation until elements are explicitly requested.
|
|
|
|
---
|
|
auto result = iota(-4, 5).map!(a => tuple(a, expensiveComputation(a)))().lazyCache();
|
|
// No computations performed at this point
|
|
|
|
auto firstElement = result.front;
|
|
// First element is now evaluated
|
