Enum twizzler_abi::upcall::UpcallMode

pub enum UpcallMode {
    Abort,
    CallSelf,
    CallSuper,
}

Possible modes for upcall handling.

Variants

Abort

Handle this upcall by immediate abort. If the SUSPEND flag is set, the thread will still abort when unsuspended.

CallSelf

Handle this upcall by calling, without trying to transfer to supervisor context. Upcall data, including frame data, will be placed on the current stack, and the thread pointer is unchanged.

CallSuper

Handle this upcall by calling into supervisor context. If the thread is already in supervisor context, this acts like UpcallMode::CallSelf. Otherwise, the thread’s stack and thread pointer are updated to the super_stack and super_thread_pointer values in the upcall target respectively, and the active security context is switched to the supervisor context (super_ctx).

Trait Implementations

impl Clone for UpcallMode

fn clone(&self) -> UpcallMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UpcallMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for UpcallMode

fn cmp(&self, other: &UpcallMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<UpcallMode> for UpcallMode

fn eq(&self, other: &UpcallMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<UpcallMode> for UpcallMode

fn partial_cmp(&self, other: &UpcallMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
