std::slice(3)

💅 std::slice — Library Functions Manual (yes bestie, the C++ one)

okay so real talk: this is std::slice from libstdc++, the C++ standard library situation, and it's filed under section 3 of the manual. she's a class, she defines a one-dimensional subset of an array, and honestly? iconic. let's get into it. 🎀

✨ NAME ✨

std::slice — a class that defines a one-dimensional subset of an array. that's it, that's the whole job, and she does it flawlessly. 💖

---

🌸 SYNOPSIS 🌸

#include <valarray>

🫶 Public Member Functions

• slice () — constructs an empty slice. yes, a whole empty slice. sometimes you just need the vibes of a slice with nothing in it. 💀
• slice (size_t __o, size_t __d, size_t __s) — constructs a slice. the real one, with actual parameters. this is the main character constructor.
• size_t size () const — returns the size of the slice. how many elements are we working with, bestie.
• size_t start () const — returns the array offset of the first slice element. where does she begin, spiritually and index-wise.
• size_t stride () const — returns the array stride of the slice. the hop distance. the step pattern. the walk. ✨

🦋 Friends

• bool operator== (const slice &, const slice &)=default — equality comparison. two slices, are they the same? =default, so the compiler handles it, and she handles it well.

🌈 Detailed Description 🌈

Class defining a one-dimensional subset of an array. (saying it again because it's true and she deserves the repetition 💅)

the slice class represents a one-dimensional subset of an array, and she's specified by three parameters: start offset, size, and stride. let's break those down fr fr:

• the start offset is the index of the first element of the array that's part of the subset. where the subset starts. her origin story.
• the size is the total number of elements in the subset. how many she's bringing to the function.
• the stride is the distance between each successive array element to include in the subset. the spacing between her picks. lowkey the most interesting one.

for example, with an array of size 10, and a slice with offset 1, size 3 and stride 2, the subset consists of array elements 1, 3, and 5. 🍓

like. the way that 1 → 3 → 5 is such a clean little pattern. ate. no cap.

and that's the whole page, bestie — shoutout to libstdc++, which is the source/version this manual page comes from, sitting pretty at the bottom under std::slice(3). go forth and slice responsibly. 💖✨🦋🌸🎀💅🫶
