All Ranges Views

All Ranges Views

A compact scan page for the main standard range views, adaptors, and adjacent range utility facilities.

How to use this reference page

Use reference pages to confirm names, categories, nearby facilities, and the constraints that matter before writing or reviewing code.

Scan the top of the page first to identify the primary types, functions, or algorithm families involved.
Use the nearby-page links when your question is really about a companion header, related algorithm family, or broader subsystem.
Validate tricky behavior with a small compileable example before relying on memory for details like invalidation, ordering, allocation, or lifetime rules.

Utility guidance

Views are lazy and usually cheap to compose.
Materialize when you need ownership, random access to a transient pipeline result, or repeated traversal over unstable input.
Keep predicates and transforms side-effect free when possible.

Example in practice

#include <ranges>
#include <vector>

int main() {
    std::vector<int> values{1, 2, 3, 4};
    auto even = values | std::views::filter([](int value) { return value % 2 == 0; });
    return *even.begin();
}
