Detailed Description

A numerical value that can be associated with an NVTX event via its event_attributes.

Example:

// Constructs a payload from the int32_t value 42
nvtx3:: event_attributes attr{nvtx3::payload{42}};
 
// `range0` will have an int32_t payload of 42
nvtx3::scoped_range range0{attr};
 
// range1 has double payload of 3.14
nvtx3::scoped_range range1{nvtx3::payload{3.14}};
