Enum multiboot2::MemoryAreaType

pub enum MemoryAreaType {
    Available,
    Reserved,
    AcpiAvailable,
    ReservedHibernate,
    Defective,
    Custom(u32),
}

Abstraction over defined memory types for the memory map as well as custom ones. Types 1 to 5 are defined in the Multiboot2 spec and correspond to the entry types of e820 memory maps.

This is not binary compatible with the Multiboot2 spec. Please use MemoryAreaTypeId instead.

Variants

Available

Available memory free to be used by the OS.

Reserved

A reserved area that must not be used.

AcpiAvailable

Usable memory holding ACPI information.

ReservedHibernate

Reserved memory which needs to be preserved on hibernation. Also called NVS in spec, which stands for “Non-Volatile Sleep/Storage”, which is part of ACPI specification.

Defective

Memory which is occupied by defective RAM modules.

Custom(u32)

Custom memory map type.

Trait Implementations

impl Clone for MemoryAreaType

fn clone(&self) -> MemoryAreaType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryAreaType

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

Formats the value using the given formatter.

impl From<MemoryAreaType> for MemoryAreaTypeId

fn from(value: MemoryAreaType) -> Self

Converts to this type from the input type.

impl From<MemoryAreaTypeId> for MemoryAreaType

fn from(value: MemoryAreaTypeId) -> Self

Converts to this type from the input type.

impl Hash for MemoryAreaType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl Ord for MemoryAreaType

fn cmp(&self, other: &MemoryAreaType) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq<MemoryAreaType> for MemoryAreaTypeId

fn eq(&self, other: &MemoryAreaType) -> 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.

impl PartialEq<MemoryAreaTypeId> for MemoryAreaType

fn eq(&self, other: &MemoryAreaTypeId) -> 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.

impl PartialEq for MemoryAreaType

fn eq(&self, other: &MemoryAreaType) -> 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.

impl PartialOrd for MemoryAreaType

fn partial_cmp(&self, other: &MemoryAreaType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
