Determine the best fitting Rust type for an integer property. This is intended for use when a specific format has not been defined in the specification. Where the minimum or maximum is not known then the returned type will default to having at least 32 bits.

Parameters:

minimum - The minimum value as set in the specification.

exclusiveMinimum - If the minimum value itself is excluded by the specification.

maximum - The maximum value as set in the specification.

exclusiveMaximum - If the maximum value itself is excluded by the specification.

preferUnsigned - Use unsigned types where the effective minimum is greater than or equal to zero.

Returns:

The Rust data type name.

exclusiveMinimum - If boundary values are excluded by the specification.

Returns:

True if the effective minimum is greater than or equal to zero.
