Implementations§

source§

impl SystemDescriptorType

source

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.

source

pub const LocalDescriptorTable: Self = _

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

source

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.

source

pub const CallGate16Bit: Self = _

Available on x86 only.

A GateDescriptor for a call to 16-bit code.

source

pub const TaskGate: Self = _

Available on x86 only.

A GateDescriptor for task switching.

source

pub const InterruptGate16Bit: Self = _

Available on x86 only.

A GateDescriptor for a 16-bit interrupt handler.

source

pub const TrapGate16Bit: Self = _

Available on x86 only.

A GateDescriptor for a 16-bit trap handler.

source

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.

source

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.

source

pub const CallGate: Self = _

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

source

pub const InterruptGate: Self = _

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

source

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.

source

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).

source§

impl SystemDescriptorType

source

pub fn is_gate(self) -> bool

Indicates that this is a GateDescriptor.
