dispenso::DefaultConcurrentVectorSizeTraits< T > Struct Template Reference

#include <concurrent_vector.h>

Static Public Attributes
static constexpr size_t	kDefaultCapacity = (sizeof(T) >= 256) ? 2 : 512 / sizeof(T)
	This is the starting user-expected capacity in number of elements (algorithm may provide more based on kReallocStrategy)
static constexpr size_t	kMaxVectorSize
	The maximum possible size for the vector.

Detailed Description

template<typename T>
struct dispenso::DefaultConcurrentVectorSizeTraits< T >

The default ConcurrentVector traits type for defining capacities and max capacities. Both members are required should one wish to supply a custom set of traits.

Member Data Documentation

kDefaultCapacity

template<typename T >

constexpr size_t dispenso::DefaultConcurrentVectorSizeTraits< T >::kDefaultCapacity = (sizeof(T) >= 256) ? 2 : 512 / sizeof(T)

staticconstexpr

This is the starting user-expected capacity in number of elements (algorithm may provide more based on kReallocStrategy)

Definition at line 95 of file concurrent_vector.h.

kMaxVectorSize

template<typename T >

constexpr size_t dispenso::DefaultConcurrentVectorSizeTraits< T >::kMaxVectorSize

staticconstexpr

Initial value:

=
      (size_t{1} << (sizeof(size_t) * CHAR_BIT > 47 ? 47 : sizeof(size_t) * CHAR_BIT - 1)) /
      sizeof(T)

The maximum possible size for the vector.

The reason this exists is because if someone doesn't require vectors of length in e.g. petabytes, the class can use less space. Additionally, some minor optimizations may be possible if the max size is less than 32-bits.
