Provides information about a shader constant (uniform) value.
| ArraySize | The number of elements in this constant. If this value is greater than 1, the constant is an array. |
| Columns | If the constant is a matrix or vector type, this stores the number of columns. Otherwise, the value is 0. |
| ConstantType | This constant's type. |
| DataType | The element data type of this constant. |
| Index | The index of this constant in its buffer. Typically, this is the byte offset from the start of the cbuffer, but depending on the platform, it may indicate another type of index. |
| Name | The name of this constant. |
| Rows | If the constant is a matrix type, this stores the number of rows. If the constant is a vector type, this value will be 1. Otherwise, the value is 0. |
| StructFields | If the constant is a struct, this stores the fields of that struct. Otherwise, the value is null. |
| StructSize | If the constant is a struct, this stores the size (in bytes) of the struct. Otherwise, the value is 0. |
