Expand description

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

Implementations§

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.

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

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.

Available on x86 only.

A GateDescriptor for a call to 16-bit code.

Available on x86 only.

A GateDescriptor for task switching.

Available on x86 only.

A GateDescriptor for a 16-bit interrupt handler.

Available on x86 only.

A GateDescriptor for a 16-bit trap handler.

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

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

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

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

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.

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).

Indicates that this is a GateDescriptor.
