Enum frame_allocator::MemoryRegionType

pub enum MemoryRegionType {
    Free,
    Reserved,
    Unknown,
}

Types of physical memory. See each variant’s documentation.

Variants

Free

Memory that is available for any general purpose.

Reserved

Memory that is reserved for special use and is only ever allocated from if specifically requested. This includes custom memory regions added by third parties, e.g., device memory discovered and added by device drivers later during runtime.

Unknown

Memory of an unknown type. This is a default value that acts as a sanity check, because it is invalid to do any real work (e.g., allocation, access) with an unknown memory region.

Trait Implementations

impl Clone for MemoryRegionType

fn clone(&self) -> MemoryRegionType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryRegionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<MemoryRegionType> for MemoryRegionType

fn eq(&self, other: &MemoryRegionType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
