pub enum VarVTypeAttr {
    VType,
}

Variants

VType

• Modifiable: Yes
• Type: char

Variable type (‘C’ for continuous, ‘B’ for binary, ‘I’ for integer, ‘S’ for semi-continuous, or ‘N’ for semi-integer). Binary variables must be either 0 or 1. Integer variables can take any integer value between the specified lower and upper bounds. Semi-continuous variables can take any value between the specified lower and upper bounds, or a value of zero. Semi-integer variables can take any integer value between the specified lower and upper bounds, or a value of zero.

Refer to this section for more information on variable types.
