get

pub fn get(self: *Pool, tag: *const anyopaque, mode: Pool.GetMode, slot: *Slot) Pool.GetError!void

• Non-blocking acquisition.
• Calls on_get hook.
• Moves the handle — slot.* set to non-null on success.
• Assert:
• slot.* == null
• Pool initialized.
• Tag registered.

get_wait

pub fn get_wait(self: *Pool, tag: *const anyopaque, slot: *Slot, timeout_ns: ?u64) (Pool.GetError || Cancelable || error{Timeout})!void

• Blocking acquisition.
• null timeout = wait forever.
• timeout_ns = 0 returns error.Timeout immediately.
• Logically equivalent to get(.available_only), but a different error (error.Timeout vs error.NotAvailable).
• Intentional: get_wait always uses the timeout error set, regardless of the timeout value.
• Calls on_get hook.
• Assert:
• slot.* == null
• Pool initialized.
• Tag registered.
