Struct rkyv::traits::CopyOptimization

source · 
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>

source

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).

source

pub const unsafe fn enable_if(value: bool) -> Self

Returns a CopyOptimization hint with the optimization enabled for T if value is true.

§Safety

T must not have any uninit bytes (e.g. padding) if value is true.

source

pub const fn disable() -> Self

Returns a CopyOptimization hint with the optimization disabled for T.

source

pub const fn is_enabled(&self) -> bool

Returns whether the optimization is enabled for T.
