Exposure to air or oxygen causes the brownish film on copper piping. Water - especially mineralized water - causes greenish or bluish corrosion. And deionized water can pull copper metal from the piping and cause pitting or damage.
The term "rusting" is reserved for the corrosion of iron.
Copper does not rust. Rust is a mixture of hydrated iron oxides so, by definition, if will only form on iron and iron-rich materials (such as some types of steel). Copper can get a covering of Verdigris, which is a green-colored compound.

Why do pennys rust?
Pennies do not rust because they are made of copper-plated zinc. However, the copper plating can react with certain acids and chemicals, causing them to tarnish or develop a patina over time. This is different from rust, which is the result of iron or steel reacting with oxygen and water.
