Enum MemoryRegionType

pub enum MemoryRegionType {
    Usable,
    Reserved,
    SoftReserved,
    AcpiData,
    AcpiNvs,
    Unusable,
    Persistent,
    Unknown,
    NonAcpi(String),
}

The types of memory address ranges distinguished by the kernel.

These largely correspond to the ACPI Address Range Types as defined in the kernel’s e820_type enum (with some minor changes).

UEFI provides even more fine-grained Memory Types, but the kernel maps those to the basic ACPI types in do_add_efi_memmap (according to the specified UEFI–ACPI Mapping).

Variants

Usable

Reserved

SoftReserved

AcpiData

AcpiNvs

Unusable

Persistent

Unknown

An E820 type not known to the kernel.

NonAcpi(String)

Any type not part of the ACPI specification, such as an MMIO range.

Trait Implementations

impl Debug for MemoryRegionType

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

Formats the value using the given formatter.

impl Display for MemoryRegionType

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

Formats the value using the given formatter.

impl From<&str> for MemoryRegionType

fn from(s: &str) -> Self

Return the enum variant for a given address range type as printed by the kernel.

This mapping is derived from the e820_type_to_string function.

impl PartialEq for MemoryRegionType

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

Tests for self and other values to be equal, and is used by ==.

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

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