pub struct CopyOptimization<T: ?Sized>(/* private fields */);
Expand description
An optimization hint about whether T
is trivially copyable.
Implementations§
Source§impl<T: ?Sized> CopyOptimization<T>
impl<T: ?Sized> CopyOptimization<T>
Sourcepub const unsafe fn enable() -> Self
pub const unsafe fn enable() -> Self
Returns a CopyOptimization
hint with the optimization enabled for T
.
§Safety
T
must not have any uninit bytes (e.g. padding).
Sourcepub const unsafe fn enable_if(value: bool) -> Self
pub const unsafe fn enable_if(value: bool) -> Self
Returns a CopyOptimization
hint with the optimization enabled for T
if value
is
true
.

Sourcepub const fn disable() -> Self
pub const fn disable() -> Self
Returns a CopyOptimization
hint with the optimization disabled for T
.
Sourcepub const fn is_enabled(&self) -> bool
pub const fn is_enabled(&self) -> bool
Returns whether the optimization is enabled for T
.
