Function useSpan

Execute the callback fn function with the passed span as the active span. The callback receives an ISpanScope object as its first parameter and the this context (when no thisArg is provided). Note: The callback will be executed even if the span is null.

Param: traceHost

The current trace host instance (core or AISKU instance)

Param: span

The span to set as the active span during the execution of the callback

Param: fn

the callback function that receives an ISpanScope and additional arguments

Param: thisArg

the this argument for the callback. If not provided, ISpanScope is used as this

Param: _args

Additional arguments to be passed to the function

useSpan<T, F>(traceHost, span, fn, thisArg?): ReturnType<F>
Execute the callback fn function with the passed span as the active span. The callback receives an ISpanScope object as its first parameter and the this context (when no thisArg is provided). Note: The callback will be executed even if the span is null.
Type Parameters
- T extends ITraceHost<IConfiguration, T>
