Enum CallConvention 

pub enum CallConvention {
    ClosureCall,
    DirectCall,
    TailCall,
    IndirectCall,
    BuiltinCall,
}

Call convention for a function.

Variants

ClosureCall

Standard closure call (through the closure mechanism).

DirectCall

Direct call (function is known at compile time).

TailCall

Tail call (reuse the current stack frame).

IndirectCall

Indirect call (through a function pointer).

BuiltinCall

Built-in operation (handled specially by the runtime).

Implementations

impl CallConvention

pub fn supports_tco(&self) -> bool

Check if this convention supports tail call optimization.

pub fn is_direct(&self) -> bool

Check if this is a direct (non-closure) call.

Trait Implementations

impl Clone for CallConvention

fn clone(&self) -> CallConvention

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallConvention

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

Formats the value using the given formatter.

impl Display for CallConvention

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

Formats the value using the given formatter.

impl PartialEq for CallConvention

fn eq(&self, other: &CallConvention) -> 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.
