Enum CallConv 

pub enum CallConv {
    Default,
    Cold,
}

Calling convention.

Variants

Default

Cold

Preserve most caller registers across the call to reduce callsite register pressure.

Trait Implementations

impl Clone for CallConv

fn clone(&self) -> CallConv

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallConv

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

Formats the value using the given formatter.

impl Default for CallConv

fn default() -> CallConv

Returns the “default value” for a type.

impl PartialEq for CallConv

fn eq(&self, other: &CallConv) -> 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 Copy for CallConv

impl Eq for CallConv

impl StructuralPartialEq for CallConv

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
