stdgpu::vector< T, Allocator >

Detailed Description

template<typename T, typename Allocator = safe_device_allocator<T>>
class stdgpu::vector< T, Allocator >

A generic container similar to std::vector on the GPU.

Template Parameters

T	The type of the stored elements
Allocator	The allocator type

Differences to std::vector:

• index_type instead of size_type
• Manual allocation and destruction of container required
• max_size and capacity limited to initially allocated size
• No guaranteed valid state when reaching capacity limit
• Additional non-standard capacity functions full() and valid()
• insert() and erase() only implemented for special case with device_end()
• Some member functions missing
