BUFFER_USAGE_TRANSFER_SRC_BIT specifies that the buffer can be used as the source of a transfer command (see the definition of https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-pipeline-stages-transfer).

BUFFER_USAGE_TRANSFER_DST_BIT specifies that the buffer can be used as the destination of a transfer command.

BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT specifies that the buffer can be used to create a BufferView suitable for occupying a DescriptorSet slot of type DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER.

BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT specifies that the buffer can be used to create a BufferView suitable for occupying a DescriptorSet slot of type DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER.

BUFFER_USAGE_UNIFORM_BUFFER_BIT specifies that the buffer can be used in a DescriptorBufferInfo suitable for occupying a DescriptorSet slot either of type DESCRIPTOR_TYPE_UNIFORM_BUFFER or DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC.

BUFFER_USAGE_STORAGE_BUFFER_BIT specifies that the buffer can be used in a DescriptorBufferInfo suitable for occupying a DescriptorSet slot either of type DESCRIPTOR_TYPE_STORAGE_BUFFER or DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC.

BUFFER_USAGE_INDEX_BUFFER_BIT specifies that the buffer is suitable for passing as the Buffer parameter to cmdBindIndexBuffer.

BUFFER_USAGE_VERTEX_BUFFER_BIT specifies that the buffer is suitable for passing as an element of the pBuffers array to cmdBindVertexBuffers.

BUFFER_USAGE_INDIRECT_BUFFER_BIT specifies that the buffer is suitable for passing as the Buffer parameter to cmdDrawIndirect, cmdDrawIndexedIndirect, cmdDrawMeshTasksIndirectNV, cmdDrawMeshTasksIndirectCountNV, or cmdDispatchIndirect. It is also suitable for passing as the Buffer member of IndirectCommandsTokenNVX, or sequencesCountBuffer or sequencesIndexBuffer member of CmdProcessCommandsInfoNVX

BUFFER_USAGE_RAY_TRACING_BIT_NV specifies that the buffer is suitable for use in cmdTraceRaysNV and cmdBuildAccelerationStructureNV.

BUFFER_USAGE_CONDITIONAL_RENDERING_BIT_EXT specifies that the buffer is suitable for passing as the Buffer parameter to cmdBeginConditionalRenderingEXT.

BUFFER_USAGE_TRANSFORM_FEEDBACK_COUNTER_BUFFER_BIT_EXT specifies that the buffer is suitable for using as a counter buffer with cmdBeginTransformFeedbackEXT and cmdEndTransformFeedbackEXT.

BUFFER_USAGE_TRANSFORM_FEEDBACK_BUFFER_BIT_EXT specifies that the buffer is suitable for using for binding as a transform feedback buffer with cmdBindTransformFeedbackBuffersEXT.

BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT specifies that the buffer can be used to retrieve a buffer device address via getBufferDeviceAddress and use that address to access the buffer’s memory from a shader.
