Struct bitcoin_support::LockedPoolManager

pub struct LockedPoolManager { /* private fields */ }

| Singleton class to keep track of locked | (ie, non-swappable) memory, for use | in std::allocator templates. | | Some implementations of the STL allocate | memory in some constructors (i.e., | see MSVC’s vector implementation where | it allocates 1 byte of memory in the allocator.) | | Due to the unpredictable order of static | initializers, we have to make sure the | LockedPoolManager instance exists | before any other STL-based objects | that use secure_allocator are created. | So instead of having LockedPoolManager | also be static-initialized, it is created | on demand. |

Implementations

impl LockedPoolManager

pub fn instance() -> &'static mut LockedPoolManager

| Return the current instance, or create | it once |

pub fn new(_allocator_in: Box<dyn LockedPageAllocator>) -> Self

pub fn locking_failed(&mut self) -> bool

| Called when locking fails, warn the | user here |

pub fn create_instance(&mut self)

| Create a new LockedPoolManager specialized | to the OS |
