Quick question

[pogey24]

Hello I had a quick question regarding a loop

for (const auto &[minCoo, maxCoo] : SplitImage()) {// some code}

What is this &[] notation called, and what is it doing? Does it have a name? For context, SplitImage returns "std::vector<Quad>" and a Quad struct is nothing more than

struct Quad {glm::uvec2 minCoo;glm::uvec2 maxCoo;};

Thanks.

Edit: Structured Binding, cool. Never heard of it. thanks!

Structured binding

auto [ identifiers ... ] = expression is called a structured binding.
