Struct ThreadState 

pub struct ThreadState<T: RegisterStorage> {
    pub registers: RegisterState<T>,
    pub extended_pstate: ExtendedPstateState,
    pub restart_code: Option<ErrnoCode>,
    pub syscall_restart_func: Option<Box<dyn FnOnce(&mut Locked<Unlocked>, &mut CurrentTask) -> Result<SyscallResult, Errno> + Send + Sync>>,
    pub arch_width: ArchWidth,
}

The thread related information of a CurrentTask. The information should never be used outside of the thread owning the CurrentTask.

Fields

registers: RegisterState<T>

A copy of the registers associated with the Zircon thread. Up-to-date values can be read from self.handle.read_state_general_regs(). To write these values back to the thread, call self.handle.write_state_general_regs(self.thread_state.registers.into()).

extended_pstate: ExtendedPstateState

Copy of the current extended processor state including floating point and vector registers.

restart_code: Option<ErrnoCode>

The errno code (if any) that indicated this task should restart a syscall.

syscall_restart_func: Option<Box<dyn FnOnce(&mut Locked<Unlocked>, &mut CurrentTask) -> Result<SyscallResult, Errno> + Send + Sync>>

A custom function to resume a syscall that has been interrupted by SIGSTOP. To use, call set_syscall_restart_func and return ERESTART_RESTARTBLOCK. sys_restart_syscall will eventually call it.

arch_width: ArchWidth

An architecture agnostic enum indicating the width (32 or 64 bits) of the execution environment in use.

Implementations
