Module traits

Available on crate feature protected only.

Expand description

Type-level states of a Protected region.

Protected<A, PM, LM> tracks its page protection (PM, a ProtectMode) and whether its pages are locked (LM, a LockMode) in its type, so each state only exposes the operations valid for it. The aliases Locked, LockedRO, Unlocked, UnlockedRO and NoAccess name the usual combinations.

Both traits are sealed: the marker types in this module are their only implementations.

Structs§

Locked: Pages are locked into memory with mlock() (UNIX) or VirtualLock() (Windows).
NoAccess: Pages can be neither read nor written.
ReadOnly: Pages are readable but not writable.
ReadWrite: Pages are readable and writable.
Unlocked: Pages are not locked into memory.

Traits§

LockMode: Whether the pages of a Protected region are locked into memory: Locked or Unlocked.
ProtectMode: Page protection of a Protected region: ReadOnly, ReadWrite or NoAccess.
