C Specification
Bits which can be set in VkBufferCreateInfo::usage, specifying
usage behavior of a buffer, are:

} VkBufferUsageFlagBits;Description
-
VK_BUFFER_USAGE_TRANSFER_SRC_BIT specifies that the buffer can be used as the source of a transfer command (see the definition of VK_PIPELINE_STAGE_TRANSFER_BIT).
-
VK_BUFFER_USAGE_TRANSFER_DST_BIT specifies that the buffer can be used as the destination of a transfer command.
-
VK_BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT specifies that the buffer can be used to create a
VkBufferViewsuitable for occupying aVkDescriptorSetslot of type VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER. -
VK_BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT specifies that the buffer can be used to create a
VkBufferViewsuitable for occupying aVkDescriptorSetslot of type VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER. -
VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT specifies that the buffer can be used in a
VkDescriptorBufferInfosuitable for occupying aVkDescriptorSetslot either of type VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER or VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC. -
VK_BUFFER_USAGE_STORAGE_BUFFER_BIT specifies that the buffer can be used in a
VkDescriptorBufferInfosuitable for occupying aVkDescriptorSetslot either of type VK_DESCRIPTOR_TYPE_STORAGE_BUFFER or VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC. -
VK_BUFFER_USAGE_INDEX_BUFFER_BIT specifies that the buffer is suitable for passing as the
bufferparameter to vkCmdBindIndexBuffer. -
VK_BUFFER_USAGE_VERTEX_BUFFER_BIT specifies that the buffer is suitable for passing as an element of the
pBuffersarray to vkCmdBindVertexBuffers. -
VK_BUFFER_USAGE_INDIRECT_BUFFER_BIT specifies that the buffer is suitable for passing as the
bufferparameter to vkCmdDrawIndirect, vkCmdDrawIndexedIndirect, or vkCmdDispatchIndirect. -
VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT specifies that the buffer can be used to retrieve a buffer device address via vkGetBufferDeviceAddress and use that address to access the buffer’s memory from a shader.
