Enum UpcallTargetSpawnOption

#[repr(C)]
pub enum UpcallTargetSpawnOption {
    DefaultAbort,
    Inherit,
    SetTo(UpcallTarget),
}

Variants

DefaultAbort

Set all sync event handlers to abort by default. Entry addresses will be zero, and upcalls will not be issued.

Inherit

Inherit the upcall target entry address. All supervisor fields are cleared.

SetTo(UpcallTarget)

Set the upcall target directly. The following conditions must be met:

1. The super_ctx field holds the ID of the current thread’s active context (prevents priv escalation).
2. The super_entry_address is at most r-x, and at least –x in the super_ctx.
3. The super_thread_pointer is exactly rw- in the super_ctx.
4. The super_stack_pointer is exactly rw- in the super_ctx.

Trait Implementations

impl Clone for UpcallTargetSpawnOption

fn clone(&self) -> UpcallTargetSpawnOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UpcallTargetSpawnOption

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

Formats the value using the given formatter.

impl Ord for UpcallTargetSpawnOption

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for UpcallTargetSpawnOption

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for UpcallTargetSpawnOption

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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