IsBitwiseCopyable<BloombergLP::bdlt::DateTz>

This template specialization for IsBitwiseCopyable indicates that bdlt::DateTz is a bitwise copyable type.

IsBitwiseCopyable<BloombergLP::bdlt::Datetime>

This template specialization for IsBitwiseCopyable indicates that bdlt::Datetime is a bitwise copyable type.

IsBitwiseCopyable<BloombergLP::bdlt::DatetimeTz>

This template specialization for IsBitwiseCopyable indicates that bdlt::DatetimeTz is a bitwise copyable type.

IsBitwiseCopyable<bdlt::DayOfWeekSet>

IsBitwiseCopyable<bdlt::DayOfWeekSet_Iter>

IsBitwiseCopyable<BloombergLP::bdlt::Time>

This template specialization for IsBitwiseCopyable indicates that bdlt::Time is a bitwise copyable type.

IsBitwiseCopyable<BloombergLP::bdlt::TimeTz>

IsBitwiseCopyable<BloombergLP::bslh::WyHashIncrementalAlgorithm>

IsBitwiseCopyable<bdlf::MemFn<PROTOTYPE>>

IsBitwiseCopyable<t_TYPE volatile>

IsBitwiseCopyable<t_TYPE const>

IsBitwiseCopyable<t_TYPE const volatile>

IsBitwiseCopyable<t_TYPE&>

This partial specialization optimizes away a number of nested template instantiations to ensure that reference types are never bitwise copyable.

IsBitwiseCopyable<t_TYPE&&>

This partial specialization optimizes away a number of nested template instantiations to ensure that rvalue reference types are never bitwise copyable.

IsBitwiseCopyable<t_TYPE[>]

IsBitwiseCopyable<t_TYPE volatile[>]

IsBitwiseCopyable<t_TYPE const[>]

IsBitwiseCopyable<t_TYPE const volatile[>]

These partial specializations ensures that array‐of‐unknown‐bound types have the same result as their element type.
