abstract class InactiveVariable

gamnit :: InactiveVariable

Inactive shader variable, either optimized out or simple absent from the program

Returned by GamnitProgram::uniforms or GamnitProgram::attributes when the uniform has not been identified as active by the driver. Operations on instances of this class have no effects.

Act as a compatibility when a program expect a uniform to exist even in a context where the driver's compiler may have optimized it out. You must be careful when receiving an InactiveVariable as it may also silence real program errors, such type in variable name.
