Crate userfaultfd

Expand description

A Linux mechanism for handling page faults in user space.

The main way to interact with this library is to create a Uffd object with a UffdBuilder, then use the methods of Uffd from a worker thread.

See userfaultfd(2) and ioctl_userfaultfd(2) for more details.

Structs

  • EventBuffer
    Represents an opaque buffer where userfaultfd events are stored.
  • FeatureFlags
    Used with UffdBuilder to determine which features are available in the current kernel.
  • IoctlFlags
    Used with UffdBuilder and Uffd::register() to determine which operations are available.
  • RegisterMode

  • UffdBuilder
    A builder for initializing Uffd objects.
