Struct SystemDescriptorType

pub struct SystemDescriptorType(/* private fields */);

Available on x86 or x86-64 only.

Discriminate types of segment descriptors that are not code or data.

Implementations

impl SystemDescriptorType

pub const TaskStateAvailable16Bit: Self

Available on x86 only.

A SegmentDescriptor for a 16-bit task state segment (TSS) that is not currently running or waiting on a call to another task.

pub const LocalDescriptorTable: Self

A SegmentDescriptor for a segment that contains a local descriptor table.

pub const TaskStateBusy16Bit: Self

Available on x86 only.

A SegmentDescriptor for a 16-bit task state segment (TSS) that is either running or waiting on a call to another task.

pub const CallGate16Bit: Self

Available on x86 only.

A GateDescriptor for a call to 16-bit code.

pub const TaskGate: Self

Available on x86 only.

A GateDescriptor for task switching.

pub const InterruptGate16Bit: Self

Available on x86 only.

A GateDescriptor for a 16-bit interrupt handler.

pub const TrapGate16Bit: Self

Available on x86 only.

A GateDescriptor for a 16-bit trap handler.

pub const TaskStateAvailable: Self

A SegmentDescriptor for a 32/64-bit task state segment (TSS) that is not currently running or waiting on a call to another task.

pub const TaskStateBusy: Self

A SegmentDescriptor for a 32/64-bit task state segment (TSS) that is either running or waiting on a call to another task.

pub const CallGate: Self

A GateDescriptor for a call to 32/64-bit code.

pub const InterruptGate: Self

A GateDescriptor for a 32/64-bit interrupt handler.

pub const TrapGate: Self

A GateDescriptor for a 32/64-bit interrupt handler.

A trap gate works identically to an interrupt gate, except that the processor does not automatically clear FlagRegister::interrupt_enabled when it invokes the handler through a trap gate.

pub const fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

An identical method is available through the CEnum trait, but this version is declared const (which is currently unstable on traits).

impl SystemDescriptorType

pub fn is_gate(self) -> bool

Indicates that this is a GateDescriptor.

Trait Implementations

impl CEnum<u8> for SystemDescriptorType

fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

impl Clone for SystemDescriptorType

fn clone(&self) -> SystemDescriptorType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SystemDescriptorType

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

Formats the value using the given formatter.

impl Default for SystemDescriptorType

fn default() -> SystemDescriptorType

Returns the “default value” for a type.

impl From<SystemDescriptorType> for u8

fn from(enum_value: SystemDescriptorType) -> Self

Converts to this type from the input type.

impl From<u8> for SystemDescriptorType

fn from(repr: u8) -> Self

Converts to this type from the input type.

impl Hash for SystemDescriptorType

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 SystemDescriptorType

fn cmp(&self, other: &SystemDescriptorType) -> 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,

Restrict a value to a certain interval.

impl PartialEq for SystemDescriptorType

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

impl PartialOrd for SystemDescriptorType

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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