init

pub fn init(self: *Pool, hooks: Pool.Hooks) !void

• Registers hooks.
• Called once after new.
• Assert:
• Hooks tags not empty, each tag not null.
• Pool not already closed.

---

close

pub fn close(self: *Pool) void

• Can be called more than once.
• Collects all handles from all per-tag free-lists.
• Calls on_close once with the full list.
• Broadcasts to wake blocked get_wait callers.

---

destroy

pub fn destroy(pl: *Pool, alloc: std.mem.Allocator) void

• Frees the pool.
• Must be closed first.
• Calling destroy on an open pool is a programming error (panic).
