GlobalDefKind

Enum GlobalDefKind

pub enum GlobalDefKind {
    Scalar {
        etype: ExprType,
        initial_value: Option<ConstantDatum>,
    },
    Array {
        subtype: ExprType,
        dimensions: Vec<usize>,
    },
}

Expand description

Kind of a pre-defined global variable.

Variants§

Scalar

A scalar (non-array) variable.

Fields

§etype: ExprType

Type of the scalar variable.

§initial_value: Option<ConstantDatum>

Initial value for the variable. If None, the variable is initialized to its default value: 0 for numeric types and an empty string for Text. The type of the datum must match etype.

Array

A multidimensional array with the given element type and fixed dimension sizes.

Each dimension size must be positive and must fit in a u16.

Fields

§subtype: ExprType

Element type of the array.

§dimensions: Vec<usize>

Size of each dimension, in order from outermost to innermost.
