fill_impl()

template<typename VIEW , typename T >

constexpr void bsl::details::fill_impl ( VIEW &  vw, T const &  value  )

noexcept

Provides the internal implementation of the fill function. Specifically, this is the non-optimized version.

Template Parameters

VIEW	the type of view to fill
T	the type to fill the view with

Parameters

vw	the view to fill
value	what to fill the view with

fill() [1/2]

template<typename VIEW , typename T >

constexpr enable_if_t<is_copy_assignable<T>::value> bsl::fill ( VIEW &  vw, T const &  value  )

noexcept

Sets all elements of a view to "value". T must be copy assignable.

Template Parameters

T	the type that defines the values being filled

Parameters

vw	the view to fill
value	the value to set the view's elements to

Returns

return's void

Exceptions

throws

if the copy assignment of T throws
