std::experi...ool_options(3)

🦋 NAME 🦋

std::experimental::pmr::pool_options — okay so it's literally just std::experimental::pmr::pool_options. That's the whole name bestie, no cap. 💅

✨ Synopsis ✨

Defined in header <experimental/memory_resource>:

struct pool_options {

    std::size_t max_blocks_per_chunk = 0;         (library fundamentals TS)
    std::size_t largest_required_pool_block = 0;

};

So this struct, std::experimental::pmr::pool_options, contains a set of constructor options for std::experimental::pmr::synchronized_pool_resource and std::experimental::pmr::unsynchronized_pool_resource. It's giving "options bag you hand to your pool resource's constructor" energy and honestly? Obsessed. 🫶

🎀 Data members 🎀

• std::size_t max_blocks_per_chunk — the maximum number of blocks that will be allocated at once from the upstream memory resource to replenish a pool (public member object). Lowkey the "how many blocks do we grab in one haul" knob. 💖
• std::size_t largest_required_pool_block — the largest allocation size that is required to be fulfilled through the pooling mechanism (public member object). Anything bigger than this doesn't go through the pool, periodt. 🔥

⚠️ Bestie, listen: if the value of max_blocks_per_chunk is zero or greater than an implementation-defined limit, that limit is used instead. The implementation may use a smaller value than is specified and may use different values for different pools. So like... it's a vibe, not a promise. 😭

Also, if the value of largest_required_pool_block is zero or greater than an implementation-defined limit, that limit is used instead. The implementation may use a threshold greater than specified in this field. So don't come for your implementation when it does its own thing, it's literally allowed to. 💀
