Enum CallDispatch 

pub enum CallDispatch {
    Direct = 0,
    Branch = 1,
    Indirect = 2,
    Vtable = 3,
}

↦ Mechanism by which control transfers to the callee.

---

^{📍 core/ops}

---

Ordered: Direct < Branch < Indirect < Vtable.

Later variants introduce more indirection and reduce static visibility.

Variants

Direct = 0

Statically resolved call.

Boundary: the call site encodes the callee directly.

Branch = 1

Selection among a finite set via conditional branch.

Boundary: dispatch occurs by matching a discriminant.

Indirect = 2

Call via function pointer.

Boundary: callee address is loaded from memory at runtime.

Vtable = 3

Dynamic dispatch via trait object.

Boundary: method pointer resolved through a vtable.

Trait Implementations

impl Clone for CallDispatch

fn clone(&self) -> CallDispatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CallDispatch

impl Debug for CallDispatch

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

Formats the value using the given formatter.

impl Eq for CallDispatch

impl Hash for CallDispatch

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CallDispatch

fn cmp(&self, other: &CallDispatch) -> 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 CallDispatch

fn eq(&self, other: &CallDispatch) -> 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 CallDispatch

fn partial_cmp(&self, other: &CallDispatch) -> 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.
