Task import table schema

A rust implementation to read/write/validate the xml file expected in the Import Table Schema task of Data Factory.
This implementation is used in Table Schema Editor project.

Project structure

Path	Description
lib.rs	Root file referencing all modules.
table_structs.rs	Structure definition (equivalent to types in TS)
table_xml_parser.rs	To read import_table_schema xml file
table_xml_writer.rs	To write import_table_schema xml file
table_validation.rs	All business rules validations
utils.rs	Utilities functions
/tests/	All tests

Running tests

cargo test

About the parser approach

Three methods have been tested:

Method	Advantage	Drawback
use a lib that convert xml to struct, then write methods to parse	Fast to implement (until it get hard to read)	Slow, high memory usage, hard to maintain
annotation on structures (write annotion on structure to define serialization/deserialization)	Fast to implement (until it get hard to read/write especially for serialization)	Slow, high memory usage, hard to maintain
event parsing	Quickest method, low memory footprint, simpler to maintain on large xml structure

In this project the event parsing method has been chosen.
