Struct CopyOptimization 

Source 
pub struct CopyOptimization<T, U>(/* private fields */)
where
    T: ?Sized,
    U: ?Sized;
Expand description

An optimization hint about whether the conversion from T to U is equivalent to copying the raw bytes of T.

Implementations§

Source§

impl<T, U> CopyOptimization<T, U>
where T: ?Sized, U: ?Sized,

Source

pub const unsafe fn enable() -> CopyOptimization<T, U>

Returns a CopyOptimization hint with the optimization enabled.

§Safety

T and U must be the same size and must not have any uninit bytes (e.g. padding).

Source

pub const unsafe fn enable_if(value: bool) -> CopyOptimization<T, U>

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

§Safety

T and U must be the same size and must not have any uninit bytes (e.g. padding) if value is true.

Source

pub const fn disable() -> CopyOptimization<T, U>

Returns a CopyOptimization hint with the optimization disabled.

Source

pub const fn is_enabled(&self) -> bool

Returns whether the optimization is enabled.

Source

pub const fn infer_array<const N: usize>( &self, ) -> CopyOptimization<[T; N], [U; N]>

Infers whether the conversion from [T; N] to [U; N] is copy-optimizable based on the conversion from T to U.

Source

pub const fn infer_slice(&self) -> CopyOptimization<[T], [U]>

Infers whether the conversion from [T] to [U] is copy-optimizable based on the conversion from T to U.
