Trait Implementations§

source§

impl AllocateLocked for PosixLockedPageAllocator

source§

fn allocate_locked(&mut self, _len: usize, _locking_success: *mut bool)

| Allocate and lock memory pages. | | If len is not a multiple of the system | page size, it is rounded up. | | Returns nullptr in case of allocation | failure. | | If locking the memory pages could not | be accomplished it will still return | the memory, however the lockingSuccess | flag will be false. lockingSuccess | is undefined if the allocation fails. |

impl FreeLocked for PosixLockedPageAllocator

source§

fn free_locked(&mut self, _addr: *mut c_void, _len: usize)

| Unlock and free memory pages. | | Clear the memory before unlocking. |
source§

impl GetLimit for PosixLockedPageAllocator

source§

fn get_limit(&mut self) -> usize

| Get the total limit on the amount of memory | that may be locked by this process, in | bytes. Return size_t max if there is | no limit or the limit is unknown. Return | 0 if no memory can be locked at all. |
