Flux built-in functions
Built-in functions provide a foundation for working with data using Flux.
Because these functions are “built-in,” they do not require an import statement and are usable without any extra setup.
Built-in functions are grouped into the following categories:
Built-in input functions
Flux’s built-in input functions define sources of data or or display information about data sources.
Built-in output functions
Flux’s built-in output functions yield results or send data to a specified output destination.
Built-in transformation functions
Flux’s built-in transformation functions transform and shape your data in specific ways.
Built-in miscellaneous functions
Flux provides built-in miscellaneous functions that serve purposes other than retrieving, transforming, or outputting data.
Built-in testing functions
Flux’s built-in testing functions test various aspects of piped-forward data.
