Enum TaskRegister

pub enum TaskRegister {}

Available on x86 or x86-64 only.

TR: Contains a Selector referencing a SegmentDescriptor that points to the current task state segment (TSS).

Note that this type cannot be instantiated. It simply serves as a namespace for the get and set methods, which work on a Selector instance.

Implementations

impl TaskRegister

pub fn get() -> Selector

Retrieve the current value of this register

pub unsafe fn set(selector: Selector)

Update the register with the provided selector value.

The value must point to an entry in the global descriptor table (local == false) with one of the SystemDescriptorType::TaskState* types.

Safety

This register fundamentally affects memory accesses and can have an impact on memory safety.
