Thread context trait

Required Methods

fn new() -> Self

Create a new empty context

fn init( &mut self, entry_point: usize, stack_pointer: usize, kernel_stack: usize, )

Initialize context for a new thread

fn get_instruction_pointer(&self) -> usize

Get instruction pointer

fn set_instruction_pointer(&mut self, ip: usize)

Set instruction pointer

fn get_stack_pointer(&self) -> usize

Get stack pointer

fn set_stack_pointer(&mut self, sp: usize)

Set stack pointer

fn get_kernel_stack(&self) -> usize

Get kernel stack pointer

fn set_kernel_stack(&mut self, sp: usize)

Set kernel stack pointer

fn set_return_value(&mut self, value: usize)

Set return value (for syscalls, fork, etc.)

fn set_tls_base(&mut self, base: u64)

Set user TLS base for this context (FS/TP).

fn tls_base(&self) -> u64

Get user TLS base stored in this context.

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

Clone the context

fn to_task_context(&self) -> TaskContext

Convert to scheduler’s TaskContext

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
