template<Err::Flag valid>
ErrorHandler<valid>::ErrorHandler(string&& caller, const char* globalLabel = nullptr) explicit

Parameters
caller the calling function (for debugging)
globalLabel a default label to use if a function doesn't have one

Creates an instance this handler to perform ESP operations safely.

template<Err::Flag valid>
bool ErrorHandler<valid>::runCheck()

Returns whether all functions ran successfully

Performs the operations and ensures all have valid results.

template<Err::Flag valid> template<typename... Args>
ErrorHandler<valid>& ErrorHandler<valid>::operator()(esp_err_t espFuncArgs..., string label, Args... args)

Template parameters
Args the ESP function args
Parameters
espFunc the ESP function
label the function label (for debugging)
args the ESP function argument values
Returns this handler for call chaining

Function call operator to pass an ESP function, it's name and any arguments.
